7f33e7241d pwm: Changes for v3.16-rc1
The majority of these changes are cleanups and fixes across all drivers.
 Redundant error messages are removed and more PWM controllers set the
 .can_sleep flag to signal that they can't be used in atomic context.
 
 Support is added for the Broadcom Kona family of SoCs and the Intel LPSS
 driver can now probe PCI devices in addition to ACPI devices. Upon shut-
 down, the pwm-backlight driver will now power off the backlight. It also
 uses the new descriptor-based GPIO API for more concise GPIO handling.
 
 A large chunk of these changes also converts platforms to use the lookup
 mechanism rather than relying on the global number space to reference
 PWM devices. This is largely in preparation for more unification and
 cleanups in future patches. Eventually it will allow the legacy PWM API
 to be removed.

2dc24b0d06 ARM: SoC updates for 3.16 (part 2)
This is a small follow-up to the larger ARM SoC updates merged
 last week, almost entirely for the keystone platform.
 
 The main change here is to use the new dma-ranges parsing code
 that came in through Russell's ARM tree. This allows the keystone
 platform to do cache-coherent DMA and to finally support all the
 available physical memory when LPAE is enabled.
 
 Aside from this, the keystone reset driver has been rewritten,
 and there is a small bug fix to allow building the orion5x platform
 again.

e430f34ee5 net: filter: cleanup A/X name usage
The macro 'A' used in internal BPF interpreter:
 #define A regs[insn->a_reg]
was easily confused with the name of classic BPF register 'A', since
'A' would mean two different things depending on context.

This patch is trying to clean up the naming and clarify its usage in the
following way:

- A and X are names of two classic BPF registers

- BPF_REG_A denotes internal BPF register R0 used to map classic register A
  in internal BPF programs generated from classic

- BPF_REG_X denotes internal BPF register R7 used to map classic register X
  in internal BPF programs generated from classic

- internal BPF instruction format:
struct sock_filter_int {
        __u8    code;           /* opcode */
        __u8    dst_reg:4;      /* dest register */
        __u8    src_reg:4;      /* source register */
        __s16   off;            /* signed offset */
        __s32   imm;            /* signed immediate constant */
};

- BPF_X/BPF_K is 1 bit used to encode source operand of instruction
In classic:
  BPF_X - means use register X as source operand
  BPF_K - means use 32-bit immediate as source operand
In internal:
  BPF_X - means use 'src_reg' register as source operand
  BPF_K - means use 32-bit immediate as source operand

c5aec4c76a Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Ben Herrenschmidt:
 "Here is the bulk of the powerpc changes for this merge window.  It got
  a bit delayed in part because I wasn't paying attention, and in part
  because I discovered I had a core PCI change without a PCI maintainer
  ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
  probably improve it later and I didn't want to rebase to add his ack.

  There is going to be a bit more next week, essentially fixes that I
  still want to sort through and test.

  The biggest item this time is the support to build the ppc64 LE kernel
  with our new v2 ABI.  We previously supported v2 userspace but the
  kernel itself was a tougher nut to crack.  This is now sorted mostly
  thanks to Anton and Rusty.

  We also have a fairly big series from Cedric that add support for
  64-bit LE zImage boot wrapper.  This was made harder by the fact that
  traditionally our zImage wrapper was always 32-bit, but our new LE
  toolchains don't really support 32-bit anymore (it's somewhat there
  but not really "supported") so we didn't want to rely on it.  This
  meant more churn that just endian fixes.

  This brings some more LE bits as well, such as the ability to run in
  LE mode without a hypervisor (ie. under OPAL firmware) by doing the
  right OPAL call to reinitialize the CPU to take HV interrupts in the
  right mode and the usual pile of endian fixes.

  There's another series from Gavin adding EEH improvements (one day we
  *will* have a release with less than 20 EEH patches, I promise!).

  Another highlight is the support for the "Split core" functionality on
  P8 by Michael.  This allows a P8 core to be split into "sub cores" of
  4 threads which allows the subcores to run different guests under KVM
  (the HW still doesn't support a partition per thread).

  And then the usual misc bits and fixes ..."

78a3bb9e40 x86: intel-mid: add watchdog platform code for Merrifield

d2deebabae booke/watchdog: refine and clean up the codes
Basically, this patch does the following:
1. Move the codes of parsing boot parameters from setup-common.c
   to driver. In this way, code reader can know directly that
   there are boot parameters that can change the timeout.
2. Make boot parameter 'booke_wdt_period' effective.
   currently, when driver is loaded, default timeout is always
   being used in stead of booke_wdt_period.
3. Wrap up the watchdog timeout in device struct and clean up
   unnecessary codes.

1a5700bc2d The clock framework changes for 3.16 are pretty typical: mostly clock
driver additions and fixes. There are additions to the clock core code
 for some of the basic types (e.g. the common divider type has some fixes
 and featured added to it).
 
 One minor annoyance is a last-minute dependency that wasn't handled
 quite right. ba0fae3 in this pull request depends on
 include/dt-bindings/clock/berlin2.h, which is already in your tree via
 the arm-soc pull request. Building for the berlin platform will break
 when the clk tree is built on it's own, but merged into your master
 branch everything should be fine.

Merge tag 'clk-for-linus-3.16' of git://git.linaro.org/people/mike.turquette/linux into next

Pull clock framework updates from Mike Turquette:
 "The clock framework changes for 3.16 are pretty typical: mostly clock
  driver additions and fixes.  There are additions to the clock core
  code for some of the basic types (e.g. the common divider type has
  some fixes and featured added to it).

  One minor annoyance is a last-minute dependency that wasn't handled
  quite right.  Commit ba0fae3b06 ("clk: berlin: add core clock driver
  for BG2/BG2CD") in this pull request depends on
  include/dt-bindings/clock/berlin2.h, which is already in your tree via
  the arm-soc pull request.  Building for the berlin platform will break
  when the clk tree is built on it's own, but merged into your master
  branch everything should be fine"

e6b8075770 arm, unwind, LLVMLinux: Enable clang to be used for unwinding the stack
Patch to prevent warning of a buggy compiler when using clang and
the ARM_UNWIND option.

Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and
GNUC_PATCHLEVEL to 4, 2, and 1 respectively.

This version of GCC gets flagged as buggy, but it isn't actually an
issue with clang so the patch will do what it did before unless clang
is defined and then it will not report the GCC version as an issue.

76ae038287 ARM: LLVMLinux: Change "extern inline" to "static inline" in glue-cache.h
With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the wrong thing (emits code for an externally
linkable version of the inline function). "static inline" is the correct choice
instead.

745c51673e x86/boot: EFI_MIXED should not prohibit loading above 4G
commit 7d453eee36 ("x86/efi: Wire up CONFIG_EFI_MIXED") introduced a
regression for the functionality to load kernels above 4G. The relevant
(incorrect) reasoning behind this change can be seen in the commit
message,

  "The xloadflags field in the bzImage header is also updated to reflect
  that the kernel supports both entry points by setting both of
  XLF_EFI_HANDOVER_32 and XLF_EFI_HANDOVER_64 when CONFIG_EFI_MIXED=y.
  XLF_CAN_BE_LOADED_ABOVE_4G is disabled so that the kernel text is
  guaranteed to be addressable with 32-bits."

This is obviously bogus since 32-bit EFI loaders will never place the
kernel above the 4G mark. So this restriction is entirely unnecessary.

But things are worse than that - since we want to encourage people to
always compile with CONFIG_EFI_MIXED=y so that their kernels work out of
the box for both 32-bit and 64-bit firmware, commit 7d453eee36
effectively disables XLF_CAN_BE_LOADED_ABOVE_4G completely.

Remove the overzealous and superfluous restriction and restore the
XLF_CAN_BE_LOADED_ABOVE_4G functionality.

broken wrt the arch/arm/mach-mvebu/board-v7.c file, leaving in a stale
l2x0_of_init() call (it's now handled by the DT description).

Which is kind of embarrassing, since I knew about it as it wasn't the
only file that had similar merge issues.  At least I got the other ones
right.
