…t/torvalds/linux into upstream-fixes

Sync with Linus' tree. This is necessary to have a base for
patch that fixes commit 35b4c01 ("power_supply: add "powers"
links to self-powered HID devices") which went in through Anton's
tree.

Description:
The /sys/devices/.../msi_irqs directory contains a variable set

corresponding msi irq vector allocated to that device. Each
numbered sub-directory N contains attributes of that irq.

What: Attribute for calibrating ST-Ericsson AB8500 Real Time Clock
Date: Oct 2011
KernelVersion: 3.0
Contact: Mark Godfrey <mark.godfrey@stericsson.com>
Description: The rtc_calibration attribute allows the userspace to
calibrate the AB8500.s 32KHz Real Time Clock.
Every 60 seconds the AB8500 will correct the RTC's value
by adding to it the value of this attribute.
The range of the attribute is -127 to +127 in units of
30.5 micro-seconds (half-parts-per-million of the 32KHz clock)
Users: The /vendor/st-ericsson/base_utilities/core/rtc_calibration
daemon uses this interface.

which can cover any part of it, block aligned, called DPS.
The protection has information embedded whether it blocks reads,
