2c2e6ecfd0 powerpc/powernv/cpuidle: Back-end cpuidle driver for powernv platform.
Following patch ports the cpuidle framework for powernv
platform and also implements a cpuidle back-end powernv
idle driver calling on to power7_nap and snooze idle states.

3fa8cad82b powerpc/pseries/cpuidle: smt-snooze-delay cleanup.
smt-snooze-delay was designed to disable NAP state or delay the entry
to the NAP state prior to adoption of cpuidle framework. This
is per-cpu variable. With the coming of CPUIDLE framework,
states can be disabled on per-cpu basis using the cpuidle/enable
sysfs entry.

Also, with the coming of cpuidle driver each state's target residency
is per-driver unlike earlier which was per-device. Therefore,
the per-cpu sysfs smt-snooze-delay which decides the target residency
of the idle state on a particular cpu causes more confusion to the user
as we cannot have different smt-snooze-delay (target residency)
values for each cpu.

In the current code, smt-snooze-delay functionality is completely broken.
It makes sense to remove smt-snooze-delay from idle driver with the
coming of cpuidle framework.
However, sysfs files are retained as ppc64_util currently
utilises it. Once we fix ppc64_util, propose to clean
up the kernel code.

d765ff23e3 powerpc: Fix 32-bit frames for signals delivered when transactional
Commit d31626f70b ("powerpc: Don't corrupt transactional state when
using FP/VMX in kernel") introduced a bug where the uc_link and uc_regs
fields of the ucontext_t that is created to hold the transactional
values of the registers in a 32-bit signal frame didn't get set
correctly.  The reason is that we now clear the MSR_TS bits in the MSR
in save_tm_user_regs(), before the code that sets uc_link and uc_regs.
To fix this, we move the setting of uc_link and uc_regs into the same
if statement that selects whether to call save_tm_user_regs() or
save_user_regs().

67bfa0ee66 powerpc/iommu: Fix initialisation of DART iommu table
Commit d084775738 switched the generic
powerpc iommu backend code to use the it_page_shift field to determine
page size. Commit 3a553170d3 should have
initiliased this field for all platforms, however the DART iommu table
code was not updated.

This commit initialises the it_page_shift field to 4K for the DART
iommu.

     etc...

   - Support for retrieving memory error information from the service
     processor on IBM servers running without a hypervisor and routing
     them to the memory poison infrastructure.

   - _PAGE_NUMA support on server processors

   - 32-bit BookE relocatable kernel support

   - FSL e6500 hardware tablewalk support

   - A bunch of new/revived board support

   - FSL e6500 deeper idle states and altivec powerdown support

Pull powerpc mremap fix from Ben Herrenschmidt:
 "This is the patch that I had sent after -rc8 and which we decided to
  wait before merging.  It's based on a different tree than my -next

  is based on -rc1) so I left it as a separate branch for your to pull.
  It's identical to the request I did 2 or 3 weeks back.

  This fixes crashes in mremap with THP on powerpc.

  The fix however requires a small change in the generic code.  It moves
  a condition into a helper we can override from the arch which is
  harmless, but it *also* slightly changes the order of the set_pmd and
  the withdraw & deposit, which should be fine according to Kirill (who
  wrote that code) but I agree -rc8 is a bit late...

4ce7a8697c x86: revert wrong memblock current limit setting
Dave reported big numa system booting is broken.

It turns out that commit 5b6e529521 ("x86: memblock: set current limit
to max low memory address") sets the limit to low wrongly.

max_low_pfn_mapped is different from max_pfn_mapped.
max_low_pfn_mapped is always under 4G.

That will memblock_alloc_nid all go under 4G.

Revert 5b6e529521 to fix a no-boot regression which was triggered by

7179ba5288 powerpc: Implement arch_spin_is_locked() using arch_spin_value_unlocked()
At a glance these are just the inverse of each other. The one subtlety
is that arch_spin_value_unlocked() takes the lock by value, rather than
as a pointer, which is important for the lockref code.

On the other hand arch_spin_is_locked() doesn't really care, so
implement it in terms of arch_spin_value_unlocked().

3405d230b3 powerpc: Add support for the optimised lockref implementation
This commit adds the architecture support required to enable the
optimised implementation of lockrefs.

That's as simple as defining arch_spin_value_unlocked() and selecting
the Kconfig option.

We also define cmpxchg64_relaxed(), because the lockref code does not
need the cmpxchg to have barrier semantics.

Using Linus' test case[1] on one system I see a 4x improvement for the
basic enablement, and a further 1.3x for cmpxchg64_relaxed(), for a
total of 5.3x vs the baseline.

On another system I see more like 2x improvement.

'readelf' shows that 'NOTE' is placed in wrong location
which is out of virtual and physical load addresses.

c1120542b9 microblaze: Add support for CCF
Add support for CCF for Microblaze.

Old binding:
system_timer: system-timer@41c00000 {

2d2e7d195b spi: Updates for v3.14
A respun version of the merges for the pull request previously sent with
 a few additional fixes.  The last two merges were fixed up by hand since
 the branches have moved on and currently have the prior merge in them.
 
 Quite a busy release for the SPI subsystem, mostly in cleanups big and
 small scattered through the stack rather than anything else:
 
  - New driver for the Broadcom BC63xx HSSPI controller.
  - Fix duplicate device registration for ACPI.
  - Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
    changes upon which the transiton depends).
  - Some small optimisations to reduce the amount of time we hold locks
    in the datapath, eliminate some redundant checks and the size of a
    spi_transfer.
  - Lots of fixes, cleanups and general enhancements to drivers,
    especially the rspi and Atmel drivers.

  The code hasn't been in linux-next for long (as I was out of it and

  accomplish it.  One driver is in thermal subsystem, the TI SoC
  thermal, and the other two drivers are in hwmon subsystem.

  Actually, this would be the first step of the complete work because we
  still need to check other potential drivers to be converted and then
  validate the proposed API.  But the reason why I include it in this
  pull request is that, first, this change does not hurt any others
  without using this approach, second, the principle and concept of this
  change would not break after converting the remaining drivers.  BTW,
  as you can see, there are several points in this change that do not
  belong to thermal subsystem.  Because it has been suggested by Guenter
  R that in such cases, it is recommended to send the complete series
  via one single subsystem.

  Specifics:

   - representing hardware thermal properties in device tree
     infrastructure

   - fix a regression that the imx thermal driver breaks system suspend.

   - introduce ACPI INT3403 thermal driver to retrieve temperature data
     from the INT3403 ACPI device object present on some systems.

   - introduce debug statement for thermal core and step_wise governor.

   - assorted fixes and cleanups for thermal core, cpu cooling, exynos
     thrmal, intel powerclamp and imx thermal driver"

09da8dfa98 ACPI and power management updates for 3.14-rc1
- ACPI core changes to make it create a struct acpi_device object for every
    device represented in the ACPI tables during all namespace scans regardless
    of the current status of that device.  In accordance with this, ACPI hotplug
    operations will not delete those objects, unless the underlying ACPI tables
    go away.
 
  - On top of the above, new sysfs attribute for ACPI device objects allowing
    user space to check device status by triggering the execution of _STA for
    its ACPI object.  From Srinivas Pandruvada.
 
  - ACPI core hotplug changes reducing code duplication, integrating the
    PCI root hotplug with the core and reworking container hotplug.
 
  - ACPI core simplifications making it use ACPI_COMPANION() in the code
    "glueing" ACPI device objects to "physical" devices.
 
  - ACPICA update to upstream version 20131218.  This adds support for the
    DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug
    facilities.  From Bob Moore, Lv Zheng and Betty Dall.
 
  - Init code change to carry out the early ACPI initialization earlier.
    That should allow us to use ACPI during the timekeeping initialization
    and possibly to simplify the EFI initialization too.  From Chun-Yi Lee.
 
  - Clenups of the inclusions of ACPI headers in many places all over from
    Lv Zheng and Rashika Kheria (work in progress).
 
  - New helper for ACPI _DSM execution and rework of the code in drivers
    that uses _DSM to execute it via the new helper.  From Jiang Liu.
 
  - New Win8 OSI blacklist entries from Takashi Iwai.
 
  - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo,
    Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria,

Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.

     execution of _STA for its ACPI object.  From Srinivas Pandruvada.

7e21774db5 The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions of
 existing drivers to the common-clock Device Tree binding, and a few
 non-critical fixes to the framework.
 
 Due to an entirely unnecessary cyclical dependency with the arm-soc tree
 this pull request is broken into two pieces. The second piece will be
 sent out after arm-soc sends you the pull request that merged in core
 support for the HiSilicon 3620 platform. That same pull request from
 arm-soc depends on this pull request to merge in those HiSilicon bits
 without causing build failures.
