Pull ARM SoC fixes from Olof Johansson:
 "A smallish batch of fixes, a little more than expected this late, but
  all fixes are contained to their platforms and seem reasonably low
  risk:

   - a somewhat large SMP fix for ux500 that still seemed warranted to
     include here
   - OMAP DT fixes for pbias regulator specification that broke due to
     some DT reshuffling
   - PCIe IRQ routing bugfix for i.MX
   - networking fixes for keystone
   - runtime PM for OMAP GPMC
   - a couple of error path bug fixes for exynos"

Merge x86 fixes from Ingo Molnar:
 "Two followup fixes related to the previous LDT fix"

Also applied a further FPU emulation fix from Andy Lutomirski to the
branch before actually merging it.

  x86/ldt: Further fix FPU emulation
  x86/ldt: Correct FPU emulation access to LDT
  x86/ldt: Correct LDT access in single stepping logic

The previous fix confused a selector with a segment prefix.  Fix it.

Compile-tested only.

ARM: Couple of Keysyone MDIO DTS fixes for 4.2-rc6+

These are necessary to get the NIC card working on all Keystone
EVMs. Couple of boards are broken without these two fixes.

Commit 4c21b8fd8f14 ("MIPS: seccomp: Handle indirect system calls (o32)")
fixed indirect system calls on O32 but it also introduced a bug for MIPS64
where it erroneously modified the v0 (syscall) register with the assumption
that the sycall offset hasn't been taken into consideration. This breaks
seccomp on MIPS64 n64 and n32 ABIs. We fix this by replacing the addition
with a move instruction.

Pull ARM fixes from Russell King:
 "Another few small ARM fixes, mostly addressing some VDSO issues"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 8410/1: VDSO: fix coarse clock monotonicity regression
  ARM: 8409/1: Mark ret_fast_syscall as a function
  ARM: 8408/1: Fix the secondary_startup function in Big Endian case
  ARM: 8405/1: VDSO: fix regression with toolchains lacking ld.bfd executable

Commit 3f5159a9221f ("x86/asm/entry/32: Update -ENOSYS handling to match
the 64-bit logic") broke the ENOSYS handling for the 32-bit compat case.
The proper error return value was never loaded into %rax, except if
things just happened to go through the audit paths, which ended up
reloading the return value.

This moves the loading or %rax into the normal system call path, just to
make sure the error case triggers it.  It's kind of sad, since it adds a
useless instruction to reload the register to the fast path, but it's
not like that single load from the stack is going to be noticeable.
