  efi: libstub: Preserve .debug sections after absolute relocation check (2017-01-31 13:11:19 +0000)

NOTE: the BGRT patch touches drivers/acpi, but lacks an ack from the ACPI
      maintainers. They have been cc'ed on the patch (and on this pull
      request).

----------------------------------------------------------------
* Wire up the UEFI memory attributes table for x86. This eliminates any
  runtime memory regions that are both writable and executable on recent
  firmware versions. (Sai Praneeth)

* Move the BGRT init code to an earlier stage so that we can still use
  efi_mem_reserve() (Dave Young)

* Preserve debug symbols in the ARM/arm64 UEFI stub (Ard)

* Some deduplication work and various other cleanups

----------------------------------------------------------------
Ard Biesheuvel (2):
      efi: Use typed function pointers for runtime services table
      efi: libstub: Preserve .debug sections after absolute relocation check

Colin Ian King (1):
      efi/esrt: Fix spelling mistake "doen't"

Dave Young (2):
      efi/x86: Move EFI BGRT init code to early init code
      efi/x86: Add debug code to print cooked memmap

Lukas Wunner (2):
      efi: Deduplicate efi_file_size() / _read() / _close()
      x86/efi: Deduplicate efi_char16_printk()

Sai Praneeth (3):
      efi: Make EFI_MEMORY_ATTRIBUTES_TABLE initialization common across all architectures
      efi: Introduce EFI_MEM_ATTR bit and set it from memory attributes table
      x86/efi: Add support for EFI_MEMORY_ATTRIBUTES_TABLE
