[GIT PULL] arm64: post merge-window fixes for 3.17

[Will Deacon]

Hi Linus,

Please can you pull the following small set of arm64 fixes to address some
issues introduced during the merge window? There's one change outside of
arch/arm64, which wires up memfd_create for asm-generic unistd.h. Arnd
suggested that we take that via the arm64 tree [1].

Thanks,

Will

arm64 fixes for merge window fallout

This small set of fixes addresses a few issues introduced during the
merge window, including:

  - Fix typo in I-cache detection that was causing us to treat all
    I-caches as aliasing
  - Hook up memfd_create and getrandom syscalls for native and compat
  - Revert a temporary hack for defconfig builds in -next (the audit
    tree changes didn't make it in this merge window)
  - A couple of UEFI fixes for TEXT_OFFSET fuzzing and /memreserve/
  - A simple sparsemem fix for 48-bit physical addressing
  - Small defconfig updates to get autotesters working with X-gene
