Andy Shevchenko f0295a36dc intel_scu_ipc: move error check out of the loop
This is small performance optimization of the busy_loop().

While here, use BIT() macro instead of plain integers when check the status.

Hans de Goede 4690555e13 samsung-laptop: Add use_native_backlight quirk, and enable it on some models
Since kernel 3.14 the backlight control has been broken on various Samsung
Atom based netbooks. This has been bisected and this problem happens since
commit b35684b8fa ("drm/i915: do full backlight setup at enable time")

This has been reported and discussed in detail here:
http://lists.freedesktop.org/archives/intel-gfx/2014-July/049395.html

Unfortunately no-one has been able to fix this. This only affects Samsung
Atom netbooks, and the Linux kernel and the BIOS of those laptops have never
worked well together. All affected laptops already have a quirk to avoid using
the standard acpi-video interface and instead use the samsung specific SABI
interface which samsung-laptop uses. It seems that recent fixes to the i915
driver have also broken backlight control through the SABI interface.

The intel_backlight driver OTOH works fine, and also allows for finer grained
backlight control. So add a new use_native_backlight quirk, and replace the
broken_acpi_video quirk with this quirk for affected models. This new quirk
disables acpi-video as before and also stops samsung-laptop from registering
the SABI based samsung_laptop backlight interface, leaving only the working
intel_backlight interface.

This commit enables this new quirk for 3 models which are known to be affected,
chances are that it needs to be used on other models too.

Azael Avalos 172ce0a9f6 toshiba_acpi: Add support for USB Sleep and Music
Newer Toshiba laptops now come with a feature called USB Sleep and
Music, where the laptop speakers remain powered and the line-in jack
is used to connect an external device to use the laptop speakers when
the computer is asleep or turned off.

This patchs adds support to such feature, by creating a sysfs entry
named "usb_sleep_music", accepting only two values, 0 to disable and
1 to enable.

Azael Avalos bb3fe01ff6 toshiba_acpi: Add support for USB Rapid Charge
Newer Toshiba laptops equipped with USB 3.0 ports now have the
functionality of rapid charging devices connected to their USB hubs.

This patch adds support to use such feature by creating a sysfs entry
named "usb_rapid_charge", accepting only two values, 0 to disable and
1 to enable, however, the machine needs a restart everytime the
function is toggled.

Azael Avalos 182bcaa5c9 toshiba_acpi: Add support for USB Sleep functions under battery
Toshiba laptops supporting USB Sleep and Charge also come with a
feature called "USB functions under battery", which what it does when
enabled, is allows the USB Sleep functions when the computer is under
battery power.

This patch adds support to that function, creating a sysfs entry
named "sleep_functions_on_battery", accepting values from 0-100,
where zero disables the function and 1-100 sets the battery level at
which point the USB Sleep functions will be disabled, and printing
the current state of the functon and also the battery level currently
set.

Azael Avalos e26ffe5124 toshiba_acpi: Add support for USB Sleep and Charge function
Newer Toshiba models now come with a feature called Sleep and Charge,
where the computer USB ports remain powered when the computer is
asleep or turned off.

This patch adds support to such feature, creating a sysfs entry
called "usb_sleep_charge" to set the desired charging mode or to
disable it.

The sysfs entry accepts three parameters, 0, 1 and 2, beign disabled,
alternate and auto respectively.

The auto mode stands for USB conformant devices (which most are), and
the alternate mode stands for those non USB conformant devices that
require more power.

Linus Torvalds 60815cf2e0 kernel: Provide READ_ONCE and ASSIGN_ONCE
As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
 ACCESS_ONCE might fail with specific compilers for non-scalar accesses.
 
 Here is a set of patches to tackle that problem.
 
 The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure
 is larger than the machine word size memcpy is used and a warning is emitted.
 The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar
 types.
 
 This merge does not yet contain a patch that forces ACCESS_ONCE to work only
 on scalar types. This is targetted for the next merge window as Linux next
 already contains new offenders regarding ACCESS_ONCE vs. non-scalar types.

Pull eCryptfs fixes from Tyler Hicks:
 "Fixes for filename decryption and encrypted view plus a cleanup

   - The filename decryption routines were, at times, writing a zero
     byte one character past the end of the filename buffer

   - The encrypted view feature attempted, and failed, to roll its own
     form of enforcing a read-only mount instead of letting the VFS
     enforce it"

strcmp was lost when all other string functions were removed,

so any driver built as a module would not have access to this symbol.

In a similar manner, we had optimized versions of
csum_partial_copy_from_user and __do_clear_user
but no exported symbols for them, breaking bunch of other drivers
when built as a module.

At the same time, move EXPORT_SYMBOL(__copy_user) and
EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
located together with the function definition.

Pull x86 apic updates from Thomas Gleixner:
 "After stopping the full x86/apic branch, I took some time to go
  through the first block of patches again, which are mostly cleanups
  and preparatory work for the irqdomain conversion and ioapic hotplug
  support.

  Unfortunaly one of the real problematic commits was right at the
  beginning, so I rebased this portion of the pending patches without
  the offenders.

  It would be great to get this into 3.19.  That makes reworking the
  problematic parts simpler.  The usual tip testing did not unearth any
  issues and it is fully bisectible now.

  I'm pretty confident that this wont affect the calmness of the xmas
  season.

  Changes:
   - Split the convoluted io_apic.c code into domain specific parts
     (vector, ioapic, msi, htirq)
   - Introduce proper helper functions to retrieve irq specific data
     instead of open coded dereferencing of pointers
   - Preparatory work for ioapic hotplug and irqdomain conversion
   - Removal of the non functional pci-ioapic driver
   - Removal of unused irq entry stubs
   - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
     allocations for everything which is called from there.
   - Small cleanups and fixes"

Linus Torvalds 34b85e3574 powerpc updates for 3.19 batch 2
The highlight is the series that reworks the idle management on powernv, which
 allows us to use deeper idle states on those machines.
 
 There's the fix from Anton for the "BUG at kernel/smpboot.c:134!" problem.
 
 An i2c driver for powernv. This is acked by Wolfram Sang, and he asked that we
 take it through the powerpc tree.
 
 A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of the audit
 maintainers.
 
 A patch from Ben to export the symbol map of our OPAL firmware as a sysfs file,
 so that tools can use it.
 
 Also some CXL fixes, a couple of powerpc perf fixes, a fix for smt-enabled, and
 the patch to add __force to get_user() so we can use bitwise types.

Dave Jones d5e80b4b18 Update/Remove soon-to-be-dead email address
I'm leaving Red Hat at the end of December 2014, so remove all
references to my soon-to-be-dead address.

(There are some references left in the tree, that need additional
changes, I'll send those through the AGP maintainers).
