Merge tag 'efi-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/efi

Pull efi changes from Matt Fleming:

 * We don't need to carry our own formatting code in the esrt driver
   because the kobject API can do that for us - Rasmus Villemoes

 * Update the arm64 file paths in Documentation/efi-stub.txt to match
   the current tree - Alan Ott

 * Consistently preface all print statements with "efi" arch/x86 so
   that it's more obvious to users reporting problems which statements
   in the kernel log are relevant for EFI - Matt Fleming

 * Fix a boot crash in the ACPI BGRT driver and delete
   efi_lookup_mapped_addr() since it's useless now that the EFI
   mappings *only* exist in the 'efi_pgd' page table. Instead we
   always early_memremap() the BGRT memory - Sai Praneeth Prakhya
