Hi Linus,

Please pull the arm64 patches below. The EFI changes going via the arm64
tree have been acked by Matt Fleming. There is also a patch adding
sys_*stat64 prototypes to include/linux/syscalls.h, acked by Andrew
Morton.

Thanks.

  arm64: compat: Remove incorrect comment in compat_siginfo (2015-02-02 16:44:39 +0000)

----------------------------------------------------------------
arm64 updates for 3.20:

- reimplementation of the virtual remapping of UEFI Runtime Services in
  a way that is stable across kexec
- emulation of the "setend" instruction for 32-bit tasks (user
  endianness switching trapped in the kernel, SCTLR_EL1.E0E bit set
  accordingly)
- compat_sys_call_table implemented in C (from asm) and made it a
  constant array together with sys_call_table
- export CPU cache information via /sys (like other architectures)
- DMA API implementation clean-up in preparation for IOMMU support
- macros clean-up for KVM
- dropped some unnecessary cache+tlb maintenance
- CONFIG_ARM64_CPU_SUSPEND clean-up
- defconfig update (CPU_IDLE)

----------------------------------------------------------------
