Subject: [PATCH 002/163] GFS2: Change maxlen variables to size_t
This patch changes some variables (especially maxlen in function
gfs2_block_map) from unsigned int to size_t. We need 64-bit arithmetic
for very large files (e.g. 1PB) where the variables otherwise get
shifted to all 0's.

Subject: [PATCH 003/163] GFS2: Request demote when a "try" flock fails
This patch changes the flock code so that it uses the TRY_1CB flag
instead of the TRY flag on the first attempt. That forces any holding
nodes to issue a dlm callback, which requests a demote of the glock.
Then, if the "try" failed, it sleeps a small amount of time for the
demote to occur. Then it tries again, for an increasing amount of time.
Subsequent attempts to gain the "try" lock don't use "_1CB" so that
only one callback is issued.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This adds some code based on code from the Broadcom GPL tar to fix the
reboot problems on BCM4705/BCM4785. I tried rebooting my device for ~10
times and have never seen a problem. This reverts the changes in the
previous commit and adds the real fix as suggested by Rafał.
Setting bit 22 in Reg 22, sel 4 puts the BIU (Bus Interface Unit) into
async mode.
The previous commit was 316cad5c1d4daee998cd1f83ccdb437f6f20d45c [MIPS:
BCM47XX: make reboot more relaiable]

Subject: [PATCH 021/163] MIPS: Malta: Improve system memory detection for '{e,
}memsize' >= 2G
Using kstrtol to parse the "{e,}memsize" variables was wrong because this
parses signed long numbers. In case of '{e,}memsize' >= 2G, the top bit
is set, resulting to -ERANGE errors and possibly random system memory
boundaries. We fix this by replacing "kstrtol" with "kstrtoul".
We also improve the code to check the kstrtoul return value and
print a warning if an error was returned.

Subject: [PATCH 022/163] MIPS: Remove race window in page fault handling
Multicore MIPSes without I/D hardware coherency suffered from a race
condition in the page fault handler. The page table entry was
published before any pending lazy D-cache flush was committed, hence
it allowed execution of stale page cache data by other VPEs in the
system.
To make the cache handling safe we need to perform flushing already in
the set_pte_at function. MIPSes without coherent I-caches can get a
small increase in flushes due to the unavailability of the execute
flag in set_pte_at.
[ralf@linux-mips.org: outlining set_pte_at() saves a good k in a test
build, so I moved its definition from pgtable.h to cache.c.]

note: this is the location of the previous definition

This is caused by commit bda4584cd943d7 ("MIPS: Support CPU topology files

MIPS64
On MIPS64, O32 processes set both TIF_32BIT_ADDR and
TIF_32BIT_REGS so the previous condition treated O32 applications
as N32 when evaluating seccomp filters. Fix the condition to check
both TIF_32BIT_{REGS, ADDR} for the N32 AUDIT flag.

Subject: [PATCH 026/163] MIPS: scall64-o32: Fix indirect syscall detection
Commit 4c21b8fd8f14 (MIPS: seccomp: Handle indirect system calls (o32))
added indirect syscall detection for O32 processes running on MIPS64
but it did not work as expected. The reason is the the scall64-o32
implementation differs compared to scall32-o32. In the former, the v0
(syscall number) register contains the absolute syscall number
(4000 + X) whereas in the latter it contains the relative syscall
number (X). Fix the code to avoid doing an extra addition, and load
the v0 register directly to the first argument for syscall_trace_enter.
Moreover, set the .reorder assembler option in order to have better
control on this part of the assembly code.

Subject: [PATCH 027/163] MIPS: EVA: Add new EVA header
Generic code may need to perform certain operations when EVA is
enabled, for example, configure the segmentation registers during
boot. In order to avoid using more CONFIG_EVA ifdefs in the arch code,
such functions will be added in this header instead.
Initially this header contains a macro which will be used by generic
code later on during VPEs configuration on secondary cores.
All it does is to call the platform specific EVA init code in case
EVA is enabled.

Subject: [PATCH 028/163] MIPS: Malta: EVA: Rename 'eva_entry' to
'platform_eva_init'
Rename 'eva_entry' to 'platform_eva_init' as required by the new
'eva_init' macro in the eva.h header. Since this macro is now used
in a platform dependent way, it must not depend on its caller so move
the t1 register initialization inside this macro. Also set the .reorder
assembler option in case the caller may have previously set .noreorder.
This may allow a few assembler optimizations. Finally include missing
headers and document the register usage for this macro.

Subject: [PATCH 030/163] MIPS: OCTEON: make get_system_type() thread-safe
get_system_type() is not thread-safe on OCTEON. It uses static data,
also more dangerous issue is that it's calling cvmx_fuse_read_byte()
every time without any synchronization. Currently it's possible to get
processes stuck looping forever in kernel simply by launching multiple
readers of /proc/cpuinfo:
(while true; do cat /proc/cpuinfo > /dev/null; done) &
(while true; do cat /proc/cpuinfo > /dev/null; done) &
...
Fix by initializing the system type string only once during the early
boot.

Subject: [PATCH 035/163] MIPS: ZBOOT: add missing <linux/string.h> include
Commit dc4d7b37 (MIPS: ZBOOT: gather string functions into string.c)
moved the string related functions into a separate file, which might
cause the following build error, depending on the configuration:
| CC arch/mips/boot/compressed/decompress.o
| In file included from linux/arch/mips/boot/compressed/../../../../lib/decompress_unxz.c:234:0,
| from linux/arch/mips/boot/compressed/decompress.c:67:
| linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c: In function 'fill_temp':
| linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c:162:2: error: implicit declaration of function 'memcpy' [-Werror=implicit-function-declaration]
| cc1: some warnings being treated as errors
| linux/scripts/Makefile.build:308: recipe for target 'arch/mips/boot/compressed/decompress.o' failed
| make[6]: *** [arch/mips/boot/compressed/decompress.o] Error 1
| linux/arch/mips/Makefile:308: recipe for target 'vmlinuz' failed
It does not fail with the standard configuration, as when
CONFIG_DYNAMIC_DEBUG is not enabled <linux/string.h> gets included in
include/linux/dynamic_debug.h. There might be other ways for it to
get indirectly included.
We can't add the include directly in xz_dec_stream.c as some
architectures might want to use a different version for the boot/
directory (see for example arch/x86/boot/string.h).

Subject: [PATCH 038/163] arch/mips/net/bpf_jit.c: fix failure check
static int pkt_type_offset(void) returned -1 in case of failure, and actual
(positive) offset value in case of success. In the only instance of its usage,
the result was saved to local "unsigned int off" variable, which is used in a
lot of places in the same (large) function, so changing its type could cause
many warnings. So new signed int variable was added.

Subject: [PATCH 042/163] kprobes/x86: Free 'optinsn' cache when range check
fails
This patch frees the 'optinsn' slot when we get a range check error,
to prevent memory leaks.
Before this patch, cache entry in kprobe_insn_cache() won't be freed
if kprobe optimizing fails due to range check failure.

Subject: [PATCH 046/163] ARM: 8132/1: LPAE: drop wrong carry flag correction

ARM: LPAE: drop wrong carry flag correction after adding TTBR1_OFFSET
In commit 7fb00c2fca4b6c58be521eb3676cf4b4ba8dde3b ("ARM: 8114/1: LPAE:
load upper bits of early TTBR0/TTBR1") part which fixes carrying in adding
TTBR1_OFFSET to TTRR1 was wrong:
addls ttbr1, ttbr1, #TTBR1_OFFSET
adcls tmp, tmp, #0
addls doesn't update flags, adcls adds carry from cmp above:
cmp ttbr1, tmp @ PHYS_OFFSET > PAGE_OFFSET?
Condition 'ls' means carry flag is clear or zero flag is set, thus only one
case is affected: when PHYS_OFFSET == PAGE_OFFSET.
It seems safer to remove this fixup. Bug is here for ages and nobody
complained. Let's fix it separately.

Subject: [PATCH 047/163] ARM: 8133/1: use irq_set_affinity with force=false
when migrating irqs
Since commit 1dbfa187dad ("ARM: irq migration: force migration off CPU
going down") the ARM interrupt migration code on cpu offline calls
irqchip.irq_set_affinity() with the argument force=true. At the point
of this change the argument had no effect because it was not used by
any interrupt chip driver and there was no semantics defined.
This changed with commit 01f8fa4f01d8 ("genirq: Allow forcing cpu
affinity of interrupts") which made the force argument useful to route
interrupts to not yet online cpus without checking the target cpu
against the cpu online mask. The following commit ffde1de64012
("irqchip: gic: Support forced affinity setting") implemented this for
the GIC interrupt controller.
As a consequence the ARM cpu offline irq migration fails if CPU0 is
offlined, because CPU0 is still set in the affinity mask and the
validataion against cpu online mask is skipped to the force argument
being true. The following first_cpu(mask) selection always selects
CPU0 as the target.
Solve the issue by calling irq_set_affinity() with force=false from
the CPU offline irq migration code so the GIC driver validates the
affinity mask against CPU online mask and therefore removes CPU0 from
the possible target candidates.
Tested on TC2 hotpluging CPU0 in and out. Without this patch the system
locks up as the IRQs are not migrated away from CPU0.

Subject: [PATCH 048/163] [media] smiapp: Fix power count handling
The sensor may be powered by either one of its sub-devices being accessed
from the user space (an open file handle) or by its s_power() op being
called with non-zero on argument. The driver counts the users and if any
reason to keep the device powered exists it will be powered.
However, a faulty condition was used in recognising the need to power off
the sensor, leading it to be powered off every time any of its uses went
away.

important.

Subject: [PATCH 054/163] PCI: imx6: Put LTSSM in "Detect" state before
disabling it
This fixes a boot hang observed when the bootloader already enabled the
PCIe link for its own use. The fundamental problem is that Freescale
forgot to wire up the core reset, so software doesn't have a sane way to
get the core into a defined state.
According to the DW PCIe core reference manual, configuration of the core
may only happen when the LTSSM is disabled, so this is one of the first
things we need to do. Apparently this isn't safe to do when the LTSSM is in
any state other than "detect" as we observe an instant machine hang when
trying to do so while the link is already up.
As a workaround, force LTSSM into detect state right before hitting the
disable switch. There is still a race window because the LTSSM may
transition out of "detect" before we can disable it, but it's the best
we can do for now.

Subject: [PATCH 055/163] [media] Kconfig: do not select SPI bus on sub-driver
auto-select
We should not select SPI bus when sub-driver auto-select is
selected. That option is meant for auto-selecting all possible
ancillary drivers used for selected board driver. Ancillary
drivers should define needed dependencies itself.
I2C and I2C_MUX are still selected here for a reason described on
commit 347f7a3763601d7b466898d1f10080b7083ac4a3

Subject: [PATCH 058/163] [media] af9033: feed clock to RF tuner
IT9135 RF tuner clock is coming from demodulator. We need enable it
early in demod init, before any tuner I/O. Currently it is enabled
by tuner driver itself, but it is too late and performance will be
reduced as some registers are not updated correctly. Clock is
disabled automatically when demod is put onto sleep.

Subject: [PATCH 062/163] spi/rockchip: Fix the wait_for_idle() timeout
The wait_for_idle() could get unlucky and timeout too quickly.
Specifically, the old calculation was effectively:
timeout = jiffies + 1;
if (jiffies >= timeout) print warning;
From the above it should be obvious that if jiffies ticks in just the
wrong place then we'll have an effective timeout of 0.
Fix this by effectively changing the above ">=" to a ">". That gives
us an extra jiffy to finish.

Subject: [PATCH 063/163] spi/rockchip: Don't warn if SPI is busy but disabled
The reference manual from Rockchip claims this about the BSF (SPI Busy
Flag):
* 0 - SPI is idle or disabled
* 1 - SPI is actively transferring data
The above doesn't quite appear to be true. Specifically I found the
busy bit set when SPI was disabled. Let's change the WARN_ON() so we
only check the busy bit if the controller was enabled.

Subject: [PATCH 064/163] spi/rockchip: Mark DMA as optional
The Rockchip SPI controller works fine without DMA (aside from a few
warnings). The DMA property even implies this, saying:
DMA request names should include "tx" and "rx" if present.
Officially mark the properties as optional.

Subject: [PATCH 065/163] crypto: drbg - backport "fix maximum value checks on
32 bit systems"
This is a backport of commit b9347aff91ce4789619168539f08202d8d6a1177.
This backport is needed as without it the code will crash on 32-bit
systems.
The maximum values for additional input string or generated blocks is
larger than 1<<32. To ensure a sensible value on 32 bit systems, return
SIZE_MAX on 32 bit systems. This value is lower than the maximum
allowed values defined in SP800-90A. The standard allow lower maximum
values, but not larger values.
SIZE_MAX - 1 is used for drbg_max_addtl to allow
drbg_healthcheck_sanity to check the enforcement of the variable
without wrapping.

Subject: [PATCH 066/163] crypto: drbg - remove check for uninitialized DRBG
handle
The drbg_healthcheck() contained a test to call the DRBG with an
uninitialized DRBG cipher handle. As this is an inappropriate use of the
kernel crypto API to try to generate random numbers before
initialization, checks verifying for an initialized DRBG have been
removed in previous patches.
Now, the drbg_healthcheck test must also be removed.

Subject: [PATCH 070/163] x86/efi: Only load initrd above 4g on second try
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Mantas found that after commit 4bf7111f5016 ("x86/efi: Support initrd
loaded above 4G"), the kernel freezes at the earliest possible moment
when trying to boot via UEFI on Asus laptop.
Revert to old way to load initrd under 4G on first try, second try will
use above 4G buffer when initrd is too big and does not fit under 4G.
[ The cause of the freeze appears to be a firmware bug when reading
file data into buffers above 4GB, though the exact reason is unknown.
Mantas reports that the hang can be avoid if the file size is a
multiple of 512 bytes, but I've seen some ASUS firmware simply
corrupting the file data rather than freezing.
Laszlo fixed an issue in the upstream EDK2 DiskIO code in Aug 2013
which may possibly be related, commit 4e39b75e ("MdeModulePkg/DiskIoDxe:
fix source/destination pointer of overrun transfer").
Whatever the cause, it's unlikely that a fix will be forthcoming
from the vendor, hence the workaround - Matt ]

Subject: [PATCH 071/163] x86/efi: Fixup GOT in all boot code paths
Maarten reported that his Macbook pro 8.2 stopped booting after commit
f23cf8bd5c1f49 ("efi/x86: efistub: Move shared dependencies to
<asm/efi.h>"), the main feature of which is changing the visibility of
symbol 'efi_early' from local to global.
By making 'efi_early' global we end up requiring an entry in the Global
Offset Table. Unfortunately, while we do include code to fixup GOT
entries in the early boot code, it's only called after we've executed
the EFI boot stub.
What this amounts to is that references to 'efi_early' in the EFI boot
stub don't point to the correct place.
Since we've got multiple boot entry points we need to be prepared to
fixup the GOT in multiple places, while ensuring that we never do it
more than once, otherwise the GOT entries will still point to the wrong
place.

Subject: [PATCH 072/163] perf: Fix a race condition in
perf_remove_from_context()
We saw a kernel soft lockup in perf_remove_from_context(),
it looks like the `perf` process, when exiting, could not go
out of the retry loop. Meanwhile, the target process was forking
a child. So either the target process should execute the smp
function call to deactive the event (if it was running) or it should
do a context switch which deactives the event.
It seems we optimize out a context switch in perf_event_context_sched_out(),
and what's more important, we still test an obsolete task pointer when
retrying, so no one actually would deactive that event in this situation.
Fix it directly by reloading the task pointer in perf_remove_from_context().
This should cure the above soft lockup.

Subject: [PATCH 073/163] x86/mm: Apply the section attribute to the variable,
not its type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes a compilation error in clang in that a linker section
attribute can't be added to a type:
arch/x86/mm/mmap.c:34:8: error: '__section__' attribute only applies to functions and global variables struct __read_mostly
...
By moving the section attribute to the variable declaration, the
desired effect is achieved.

Subject: [PATCH 074/163] efi/arm64: Fix fdt-related memory reservation
Commit 86c8b27a01cf:
"arm64: ignore DT memreserve entries when booting in UEFI mode
prevents early_init_fdt_scan_reserved_mem() from being called for
arm64 kernels booting via UEFI. This was done because the kernel
will use the UEFI memory map to determine reserved memory regions.
That approach has problems in that early_init_fdt_scan_reserved_mem()
also reserves the FDT itself and any node-specific reserved memory.
By chance of some kernel configs, the FDT may be overwritten before
it can be unflattened and the kernel will fail to boot. More subtle
problems will result if the FDT has node specific reserved memory
which is not really reserved.
This patch has the UEFI stub remove the memory reserve map entries
from the FDT as it does with the memory nodes. This allows
early_init_fdt_scan_reserved_mem() to be called unconditionally
so that the other needed reservations are made.

Subject: [PATCH 078/163] regulator: remove unnecessary of_node_get() to parent
These of_node_get() were added to balance refcount decrements inside of
of_find_node_by_name().
See: commit c92f5dd2c42f ("regulator: Add missing of_node_put()")
However of_find_node_by_name() was then replaced by of_get_child_by_name(),
which doesn't call of_node_put() against its input parameter.
So, need to remove these unnecessary of_node_get() calls.

Subject: [PATCH 080/163] PCI: Add pci_ignore_hotplug() to ignore hotplug
events for a device
Powering off a hot-pluggable device, e.g., with pci_set_power_state(D3cold),
normally generates a hot-remove event that unbinds the driver.
Some drivers expect to remain bound to a device even while they power it
off and back on again. This can be dangerous, because if the device is
removed or replaced while it is powered off, the driver doesn't know that
anything changed. But some drivers accept that risk.
Add pci_ignore_hotplug() for use by drivers that know their device cannot
be removed. Using pci_ignore_hotplug() tells the PCI core that hot-plug
events for the device should be ignored.
The radeon and nouveau drivers use this to switch between a low-power,
integrated GPU and a higher-power, higher-performance discrete GPU. They
power off the unused GPU, but they want to remain bound to it.
This is a reimplementation of f244d8b623da ("ACPIPHP / radeon / nouveau:
Fix VGA switcheroo problem related to hotplug") but extends it to work with
both acpiphp and pciehp.
This fixes a problem where systems with dual GPUs using the radeon drivers
become unusable, freezing every few seconds (see bugzillas below). The
resume of the radeon device may also fail, e.g.,
This fixes problems on dual GPU systems where the radeon driver becomes
unusable because of problems while suspending the device, as in bug 79701:

Subject: [PATCH 083/163] ALSA: hda - Fix invalid pin powermap without jack
detection
When a driver is set up without the jack detection explicitly (either
by passing a model option or via a specific fixup), the pin powermap
of IDT/STAC codecs is set up wrongly, resulting in the silence
output. It's because of a logic failure in stac_init_power_map().
It tries to avoid creating a callback for the pins that have other
auto-hp and auto-mic callbacks, but the check is done in a wrong way
at a wrong time. The stac_init_power_map() should be called after
creating other jack detection ctls, and the jack callback should be
created only for jack-detectable widgets.
This patch fixes the check in stac_init_power_map() and its callee
at the right place, after snd_hda_gen_build_controls().

Subject: [PATCH 084/163] virtio-rng: fix stuck of hot-unplugging busy device
When we try to hot-remove a busy virtio-rng device from QEMU monitor,
the device can't be hot-removed. Because virtio-rng driver hangs at
wait_for_completion_killable().
This patch exits the waiting by completing have_data completion before
unregistering, resets data_avail to avoid the hwrng core use wrong
buffer bytes.

Subject: [PATCH 090/163] Input: atkbd - do not try 'deactivate' keyboard on
any LG laptops
We are getting more and more reports about LG laptops not having
functioning keyboard if we try to deactivate keyboard during probe.
Given that having keyboard deactivated is merely "nice to have"
instead of a hard requirement for probing, let's disable it on all
LG boxes instead of trying to hunt down particular models.
This change is prompted by patches trying to add "LG Electronics"/"ROCKY"
and "LG Electronics"/"LW60-F27B" to the DMI list.

Subject: [PATCH 095/163] PCI: Remove "no hotplug settings from platform"
warning
We print way too many messages like this:
pci 0000:00:00.0: no hotplug settings from platform
pci 0000:00:00.0: using default PCI settings
This usually happens when the platform doesn't supply an ACPI _HPP method,
but the method is optional, so there's no point in warning about it.
Not only are the messages useless, but we call pci_configure_slot() far too
many times, so they're repeated many times. I'll fix the overuse of
pci_configure_slot() too, but that will wait until the next merge window.
For now, just remove both log messages.

emulation
According to the ARM ARMv7, explicit barriers are necessary when using
synchronisation primitives such as SWP{B}. The use of these
instructions does not automatically imply a barrier and any ordering
requirements by the software must be explicitly expressed with the use
of suitable barriers.
Based on this, remove the barriers from SWP{B} emulation.

Subject: [PATCH 097/163] ARM: 8137/1: fix get_user BE behavior for target
variable with size of 8 bytes
e38361d 'ARM: 8091/2: add get_user() support for 8 byte types' commit
broke V7 BE get_user call when target var size is 64 bit, but '*ptr' size
is 32 bit or smaller. e38361d changed type of __r2 from 'register
unsigned long' to 'register typeof(x) __r2 asm("r2")' i.e before the change
even when target variable size was 64 bit, __r2 was still 32 bit.
But after e38361d commit, for target var of 64 bit size, __r2 became 64
bit and now it should occupy 2 registers r2, and r3. The issue in BE case
that r3 register is least significant word of __r2 and r2 register is most
significant word of __r2. But __get_user_4 still copies result into r2 (most
significant word of __r2). Subsequent code copies from __r2 into x, but
for situation described it will pick up only garbage from r3 register.
Special __get_user_64t_(124) functions are introduced. They are similar to
corresponding __get_user_(124) function but result stored in r3 register
(lsw in case of 64 bit __r2 in BE image). Those function are used by
get_user macro in case of BE and target var size is 64bit.
Also changed __get_user_lo8 name into __get_user_32t_8 to get consistent
naming accross all cases.

nfs4_open_and_get_state
commit 4fa2c54b5198d09607a534e2fd436581064587ed
NFS: nfs4_do_open should add negative results to the dcache.
used "d_drop(); d_add();" to ensure that a dentry was hashed
as a negative cached entry.
This is not safe if the dentry has an non-NULL ->d_inode.
It will trigger a BUG_ON in d_instantiate().
In that case, d_delete() is needed.
Also, only d_add if the dentry is currently unhashed, it seems
pointless removed and re-adding it unchanged.

Subject: [PATCH 099/163] GFS2: fix d_splice_alias() misuses
Callers of d_splice_alias(dentry, inode) don't need iput(), neither
on success nor on failure. Either the reference to inode is stored
in a previously negative dentry, or it's dropped. In either case
inode reference the caller used to hold is consumed.
__gfs2_lookup() does iput() in case when d_splice_alias() has failed.
Double iput() if we ever hit that. And gfs2_create_inode() ends up
not only with double iput(), but with link count dropped to zero - on
an inode it has just found in directory.

Subject: [PATCH 100/163] spi: davinci: request cs_gpio's from probe
Now CS GPIOs are requested from struct spi_master.setup() callback
and that causes failures when Client SPI device is getting accessed
through SPIDEV driver. The failure happens, because .setup() callback
may be called many times from IOCTL handler and when it's called
second time gpio_request() will fail and return -EBUSY.
Hence, fix it by moving CS GPIOs requesting code in .probe().

register
If touchscreen mode is enabled and a conversion is requested on another
channel, the result in the last converted data register can be a
touchscreen relative value. Starting a conversion involves to do a
conversion for all active channel. It starts with ADC channels and ends
with touchscreen channels. Then if ADC_LCD register is not read quickly,
its content may be a touchscreen conversion.
To remove this temporal constraint, the conversion value is taken from
the channel data register.

Subject: [PATCH 107/163] [CIFS] Fix setting time before epoch (negative time
values)
xfstest generic/258 sets the time on a file to a negative value
(before 1970) which fails since do_div can not handle negative
numbers. In addition 'normal' division of 64 bit values does
not build on 32 bit arch so have to workaround this by special
casing negative values in cifs_NTtimeToUnix
Samba server also has a bug with this (see samba bugzilla 7771)
but it works to Windows server.

Subject: [PATCH 110/163] vfs: simplify and shrink stack frame of
link_path_walk()
Commit 9226b5b440f2 ("vfs: avoid non-forwarding large load after small
store in path lookup") made link_path_walk() always access the
"hash_len" field as a single 64-bit entity, in order to avoid mixed size
accesses to the members.
However, what I didn't notice was that that effectively means that the
whole "struct qstr this" is now basically redundant. We already
explicitly track the "const char *name", and if we just use "u64
hash_len" instead of "long len", there is nothing else left of the
"struct qstr".
We do end up wanting the "struct qstr" if we have a filesystem with a
"d_hash()" function, but that's a rare case, and we might as well then
just squirrell away the name and hash_len at that point.
End result: fewer live variables in the loop, a smaller stack frame, and
better code generation. And we don't need to pass in pointers variables
to helper functions any more, because the return value contains all the
relevant information. So this removes more lines than it adds, and the
source code is clearer too.

Subject: [PATCH 116/163] Target/iser: Fix initiator_depth and
responder_resources
The iser target is the RDMA requester and the iser initiator is the
RDMA responder. In order to determine the max inflight RDMA READ requests
to set on the QP (initiator_depth), it should take the min between the
initiator published initiator_depth and the max inflight rdma read
requests its local HCA support (max_qp_init_rd_atom).
The target will never handle incoming RDMA READ requests so no need to
set responder_resources.

Subject: [PATCH 117/163] iscsi-target: Ignore ICF_GOT_LAST_DATAOUT during
Data-Out ITT lookup
This patch adds a explicit check in iscsit_find_cmd_from_itt_or_dump()
to ignore commands with ICF_GOT_LAST_DATAOUT set. This is done to
address the case where an ITT is being reused for DataOUT, but the
previous command with the same ITT has not yet been acknowledged by
ExpStatSN and removed from the per connection command list.
This issue was originally manifesting itself by referencing the
previous command during ITT lookup, and subsequently hitting the
check in iscsit_check_dataout_hdr() for ICF_GOT_LAST_DATAOUT, that
resulted in the DataOUT PDU + associated payload being silently
dumped.

Causes rmmod to fail for at least 7 seconds after unmount which
makes automated testing a little harder when reloading cifs.ko
between test runs.

Subject: [PATCH 119/163] cifs: remove dead code
cifs provides two dummy functions 'sess_auth_lanman' and
'sess_auth_kerberos' for the case in which the respective
features are not defined. However, the caller is also under
an #ifdef, so we just get warnings about unused code:
fs/cifs/sess.c:1109:1: warning: 'sess_auth_kerberos' defined but not used [-Wunused-function]
sess_auth_kerberos(struct sess_data *sess_data)
Removing the dead functions gets rid of the warnings without
any downsides that I can see.
(Yalin Wang reported the identical problem and fix so added him)

Subject: [PATCH 122/163] vfs: workaround gcc <4.6 build error in
link_path_walk()
Commit d6bb3e9075bb ("vfs: simplify and shrink stack frame of
link_path_walk()") introduced build problems with GCC versions older
than 4.6 due to the initialisation of a member of an anonymous union in
struct qstr without enclosing braces.
This hits GCC bug 10676 [1] (which was fixed in GCC 4.6 by [2]), and
causes the following build error:
fs/namei.c: In function 'link_path_walk':
fs/namei.c:1778: error: unknown field 'hash_len' specified in initializer
This is worked around by adding explicit braces.

Subject: [PATCH 124/163] ARM: 8148/1: flush TLS and thumbee register state
during exec
The TPIDRURO and TPIDRURW registers need to be flushed during exec;
otherwise TLS information is potentially leaked. TPIDRURO in
particular needs careful treatment. Since flush_thread basically
needs the same code used to set the TLS in arm_syscall, pull that into
a common set_tls helper in tls.h and use it in both places.
Similarly, TEEHBR needs to be cleared during exec as well. Clearing
its save slot in thread_info isn't right as there is no guarantee
that a thread switch will occur before the new program runs. Just
setting the register directly is sufficient.

INFO: lockdep is turned off.
We don't really need to get the platform irq again when we're
enabling or disabling the per-cpu irq. Furthermore, we don't
really need to set and clear bits in the active_irqs bitmask
because that's only used in the non-percpu irq case to figure out
when the last CPU PMU has been disabled. Just pass the irq
directly to the enable/disable functions to clean all this up.
This should be slightly more efficient and also fix the
scheduling while atomic bug.

Subject: [PATCH 127/163] vgaarb: Don't default exclusively to first video
device with mem+io
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 20cde694027e ("x86, ia64: Move EFI_FB vga_default_device()
initialization to pci_vga_fixup()") moved boot video device detection from
efifb to x86 and ia64 pci/fixup.c.
For dual-GPU Apple computers above change represents a regression as code
in efifb did forcefully override vga_default_device while the merge did not
(vgaarb happens prior to PCI fixup).
To improve on initial device selection by vgaarb (it cannot know if PCI
device not behind bridges see/decode legacy VGA I/O or not), move the
screen_info based check from pci_video_fixup() to vgaarb's init function and
use it to refine/override decision taken while adding the individual PCI
VGA devices. This way PCI fixup has no reason to adjust vga_default_device
anymore but can depend on its value for flagging shadowed VBIOS.
This has the nice benefit of removing duplicated code but does introduce a
#if defined() block in vgaarb. Not all architectures have screen_info and
would cause compile to fail without it.

Subject: [PATCH 129/163] Btrfs: set inode's logged_trans/last_log_commit after
ranged fsync
When a ranged fsync finishes if there are still extent maps in the modified
list, still set the inode's logged_trans and last_log_commit. This is important
in case an inode is fsync'ed and unlinked in the same transaction, to ensure its
inode ref gets deleted from the log and the respective dentries in its parent
are deleted too from the log (if the parent directory was fsync'ed in the same
transaction).
Instead make btrfs_inode_in_log() return false if the list of modified extent
maps isn't empty.
This is an incremental on top of the v4 version of the patch:
"Btrfs: fix fsync data loss after a ranged fsync"
which was added to its v5, but didn't make it on time.

Subject: [PATCH 131/163] MIPS: SmartMIPS: Disable assembler warnings
The kernel code overrides the default ISA as passed by the compiler
in quite a few places. This has unfortunate side effects when smartmips
is enabled leading to hundreds of warnings during build such as:
{standard input}: Assembler messages:
{standard input}:411: Warning: the `smartmips' extension requires MIPS32
revision 1 or greater
{standard input}: Assembler messages:
{standard input}:43: Warning: the 64-bit MIPS architecture does not support the
`smartmips' extension
[...]
Until the kernel code is fixed properly (if possible), disable all the
assembler warning messages to make the build logs readable again.
This has no runtime side effects but it makes it easier to spot
more critical warnings and problems during build.

Subject: [PATCH 132/163] Revert "init: make rootdelay=N consistent with
rootwait behaviour"
This reverts commit 4dfe694f616e00e6fd83e5bbcd7a3c4d7113493d.
In that, we did:
Here we move the rootdelay code to be right beside the rootwait code, so
that their behaviour is consistent.
...which is fine, but in hindsight, perhaps moving the rootwait to be
beside the rootdelay would have been better. We also indicated:
It should be noted that in doing so, the actions based on the
saved_root_name[0] and initrd_load() were previously put on hold by
rootdelay=N and now currently will not be delayed. However, I think
consistent behaviour is more important than matching historical behaviour
of delaying the above two operations.
But Pavel reported an instance where an ARM target with root on MMC
was failing to mount root, and Russell diagnosed it to the fact that
the call to set ROOT_DEV within the saved_root_name[0] processing
block mentioned above was no longer being delayed.
Rather than moving both wait clauses to the original position of
rootdelay and risking unearthing other possible corner case breakage
at this point in time, we simply revert now and we can revisit
trying the alternate/earlier location in another development cycle.

This reverts commit b96de000bc8bc9688b3a2abea4332bd57648a49f.
This commit is triggering failures to mount by subvolume id in some
configurations. The main problem is how many different ways this
scanning function is used, both for scanning while mounted and
unmounted. A proper cleanup is too big for late rcs.
For now, just revert the commit and we'll put a better fix into a later

Subject: [PATCH 139/163] NFSv4: nfs4_state_manager() vs.
nfs_server_remove_lists()
There is a race between nfs4_state_manager() and
nfs_server_remove_lists() that happens during a nfsv3 mount.
The v3 mount notices there is already a supper block so
nfs_server_remove_lists() called which uses the nfs_client_lock
spin lock to synchronize access to the client list.
At the same time nfs4_state_manager() is running through
the client list looking for work to do, using the same
lock. When nfs4_state_manager() wins the race to the
list, a v3 client pointer is found and not ignored
properly which causes the panic.
Moving some protocol checks before the state checking
avoids the panic.

When ending a bi-directionional SCSI request, blk_finish_request()
cleans up and frees the request, but scsi_release_bidi_buffers() tries
to indirect through the request to find it's data buffers. This causes
a panic due to a null pointer dereference.

Subject: [PATCH 155/163] USB: EHCI: unlink QHs even after the controller has
stopped
Old code in ehci-hcd tries to expedite disabling endpoints after the
controller has stopped, by destroying the endpoint's associated QH
without first unlinking the QH. This was necessary back when the
driver wasn't so careful about keeping track of the controller's
state.
But now we are careful about it, and the driver knows that when the
controller isn't running, no unlinking delay is needed. Furthermore,
skipping the unlink step will trigger a BUG() in qh_destroy() when the
preceding QH is released, because the link pointer will be non-NULL.
Removing the lines that skip the unlinking step and go directly to
QH_STATE_IDLE fixes the problem.

Hi,
The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.
I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.

Subject: [PATCH 158/163] USB: storage: Add quirks for Entrega/Xircom USB to
SCSI converters
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.
The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.
Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.
My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.
This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

Subject: [PATCH 162/163] drm/nouveau: ltc/gf100-: fix cbc issues on certain
boards
A mismatch between FB and LTC's idea of how big a large page is causes
issues such as black "holes" in rendering to occur on some boards
(those where LTC is configured for 64KiB large pages) when compression
is used.
Confirmed to fix at least the GK107 MBP.
