Merge branch 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull EFI updates from Ingo Molnar:
 "Main changes:

   - Move efivarfs from the misc filesystem section to pseudo filesystem

   - Expose firmware platform size in sysfs

   - Improve robustness of get_memory_map() by removing assumptions on
     the size of efi_memory_desc_t.

  - various cleanups and fixes

  The biggest risk is the get_memory_map() change, which changes the way
  that both the arm64 and x86 EFI boot stub build the early memory map.
  There are no known regressions with it at the moment, BYMMV"

* 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  efi: Don't look for chosen@0 node on DT platforms
  firmware: efi: Remove unneeded guid unparse
  efi/libstub: Call get_memory_map() to obtain map and desc sizes
  efi: Small leak on error in runtime map code
  efi: rtc-efi: Mark UIE as unsupported
  arm64/efi: efistub: Apply __init annotation
  efi: Expose underlying UEFI firmware platform size to userland
  efi: Rename efi_guid_unparse to efi_guid_to_str
  efi: Update the URLs for efibootmgr
  fs: Make efivarfs a pseudo filesystem, built by default with EFI
