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.
The following changes since commit eaa27f34e91a14cdceed26ed6c6793ec1d186115:

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)
