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

Pull arm64 fixes from Will Deacon:
 "Another handful of arm64 fixes here. Most of the complication comes
  from improving our kpti code to avoid lengthy pauses (30+ seconds)
  during boot when we rewrite the page tables. There are also a couple
  of IORT fixes that came in via Lorenzo.

  Summary:

   - Don't error in kexec_file_load if kaslr-seed is missing in
     device-tree

   - Fix incorrect argument type passed to iort_match_node_callback()

   - Fix IORT build failure when CONFIG_IOMMU_API=n

   - Fix kpti performance regression with new rodata default option

   - Typo fix"
