  Documentation/arm64: clarify requirements for DTB placement (2013-09-05 17:29:05 +0100)

----------------------------------------------------------------
- User tagged pointers support (top 8-bit of user pointers automatically
  ignored by the CPU).
- Kernel mode NEON (no users for arm64 yet but work in progress).
- arm64 kernel Image header extended to accommodate future EFI stub.
- Remove BogoMIPS reporting (not relevant, it's just the timer
  frequency).
- Clean-up (EM_AARCH64/EM_ARM to elf-em.h, ELF notes in read-only
  segment, unused variable).
- Bug-fixes (RAM boundaries not 2MB aligned, perf, includes).

----------------------------------------------------------------
Ard Biesheuvel (1):
      arm64: add support for kernel mode NEON

Catalin Marinas (3):
      arm64: Enable interrupts in the EL0 undef handler

      arm64: Remove unused cpu_name ascii in arch/arm64/mm/proc.S

Chen Gang (1):
      ARM64: include: asm: include "asm/types.h" in "pgtable-2level-types.h" and "pgtable-3level-types.h"

Dan Aloni (1):
      Move the EM_ARM and EM_AARCH64 definitions to uapi/linux/elf-em.h

Mark Salter (2):
      arm64: move elf notes into readonly segment

Roy Franz (1):
      arm64: Expand arm64 image header

Will Deacon (4):
      arm64: perf: fix group validation when using enable_on_exec
      arm64: perf: fix ARMv8 EVTYPE_MASK to include NSH bit
      arm64: delay: don't bother reporting bogomips in /proc/cpuinfo
      arm64: mm: permit use of tagged pointers at EL0
