Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux 

Pull arm64 fixes from Will Deacon:
 "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"
