Hi Linus,
Here's the usual mixed bag of arm64 updates, also including some related
EFI changes (Acked by Matt) and the MMU gather range cleanup (Acked by
you). Please can you pull for 3.19?
Cheers,
Will

arm64: remove the unnecessary arm64_swiotlb_init() (2014-12-05 12:19:52 +0000)
----------------------------------------------------------------
arm64 updates for 3.19
Changes include:
- Support for alternative instruction patching from Andre
- seccomp from Akashi
- Some AArch32 instruction emulation, required by the Android folks
- Optimisations for exception entry/exit code, cmpxchg, pcpu atomics
- mmu_gather range calculations moved into core code
- EFI updates from Ard, including long-awaited SMBIOS support
- /proc/cpuinfo fixes to align with the format used by arch/arm/
- A few non-critical fixes across the architecture
