[GIT PULL] EFI changes for v3.16

[Matt Fleming <matt-HNK1S37rvNbeXh+fF434Mdi2O/JbrIOy@public.gmane.org>]

Hi folks,

Please pull the following changes for v3.16. I'd like to get these in
early so that they've got plenty of time to bake in linux-next. In
particular, the ARM folks have had a hard time getting the generic EFI
cleanups/improvements picked up via other trees.

Obviously by taking these through tip we're creating a dependency with
whatever tree the ARM patches live in. Do we need to inform Stephen
Rothwell explicitly of this dependency? How should we handle things when
the v3.16 merge window opens?

The following changes since commit c9eaa447e77efe77b7fa4c953bd62de8297fd6c5:

  Linux 3.15-rc1 (2014-04-13 14:18:35 -0700)

  efivars: Add compatibility code for compat tasks (2014-04-17 13:53:53 +0100)

----------------------------------------------------------------
 * Generic EFI cleanups to help with the pending ARM/ARM64 EFI boot stub
   by reducing code duplication - Roy Franz, Leif Lindholm, Mark Salter

 * Swap to a single efi_call* implementation to reduce code duplication

 * Perform full FPU context saving/restoring where needed before making
   calls into the firmware - Ricardo Neri

 * efivars compat support to allow 32-bit userland to access the EFI
   variables via the sysfs efivars interface when running with a 64-bit
   kernel
