For various reasons Linux wants to +know in advance boot time the maximum number of CPUs that could be plugged +into the system. ACPI 3.0 currently has no official way to supply +this information from the firmware to the operating system. + +In ACPI each CPU needs an LAPIC object in the MADT table (5.2.11.5 in the +ACPI 3.0 specification).

If the CPU is not available yet +it should have its LAPIC Enabled bit set to 0. Linux will use the number +of disabled LAPICs to compute the maximum number of future CPUs. + +In the worst case the user can overwrite this choice using a command line +option (additional_cpus=...), but it is recommended to supply the correct +number (or a reasonable approximation of it, with erring towards more not less) +in the MADT to avoid manual configuration. diff --git a/trunk/MAINTAINERS b/trunk/MAINTAINERS index b6416a293ec9..0db72a36e245 100644 --- a/trunk/MAINTAINERS +++ b/trunk/MAINTAINERS @@ -2359,13 +2359,6 @@ P: Nicolas Pitre M: nico@cam.org S: Maintained -SNA NETWORK LAYER -P: Jay Schulist -M: jschlst@samba.org -L: linux-sna@turbolinux.com -W: http://www.linux-sna.org -S: Supported - SOFTWARE RAID (Multiple Disks) SUPPORT P: Ingo Molnar M: mingo@redhat.com diff --git a/trunk/arch/alpha/kernel/pci-noop.c b/trunk/arch/alpha/kernel/pci-noop.c index 9903e3a79102..fff5cf93e816 100644 --- a/trunk/arch/alpha/kernel/pci-noop.c +++ b/trunk/arch/alpha/kernel/pci-noop.c @@ -7,6 +7,7 @@ #include #include #include +#include #include #include #include diff --git a/trunk/arch/arm/common/rtctime.c b/trunk/arch/arm/common/rtctime.c index 72b03f201eb9..ffb82d5bedef 100644 --- a/trunk/arch/arm/common/rtctime.c +++ b/trunk/arch/arm/common/rtctime.c @@ -17,6 +17,7 @@ #include #include #include +#include #include #include diff --git a/trunk/arch/arm/kernel/apm.c b/trunk/arch/arm/kernel/apm.c index b9df1b782bb1..766b6c05c6db 100644 --- a/trunk/arch/arm/kernel/apm.c +++ b/trunk/arch/arm/kernel/apm.c @@ -18,6 +18,7 @@ #include #include #include +#include #include #include #include diff --git a/trunk/arch/cris/arch-v10/drivers/ds1302.c b/trunk/arch/cris/arch-v10/drivers/ds1302.c index 10795f67f687..b100f26497c4 100644 --- a/trunk/arch/cris/arch-v10/drivers/ds1302.c +++ b/trunk/arch/cris/arch-v10/drivers/ds1302.c @@ -148,6 +148,7 @@ #include #include #include +#include #include #include diff --git a/trunk/arch/cris/arch-v10/drivers/pcf8563.c b/trunk/arch/cris/arch-v10/drivers/pcf8563.c index f2c55742e90c..af517c210383 100644 --- a/trunk/arch/cris/arch-v10/drivers/pcf8563.c +++ b/trunk/arch/cris/arch-v10/drivers/pcf8563.c @@ -28,6 +28,7 @@ #include #include #include +#include #include #include diff --git a/trunk/arch/i386/Kconfig b/trunk/arch/i386/Kconfig index 815878ebd30f..d5d0df7f04fc 100644 --- a/trunk/arch/i386/Kconfig +++ b/trunk/arch/i386/Kconfig @@ -41,8 +41,21 @@ config ARCH_MAY_HAVE_PC_FDC bool default y +config DMI + bool + default y + source "init/Kconfig" +config DOUBLEFAULT + default y + bool "Enable doublefault exception handler" if EMBEDDED + help + This option allows trapping of rare doublefault exceptions that + would otherwise cause a system to silently reboot.
