  partitions/efi: Fix partition name parsing in GUID partition entry (2020-03-06 11:17:42 +0100)

----------------------------------------------------------------
More EFI updates for v5.7

- a fix for a boot regression in the IMA code on x86 booting without UEFI
- memory encryption fixes for x86, so that the TPM tables and the RNG
  config table created by the stub are correctly identified as living in
  unencrypted memory
- style tweak and doc update from Heinrich
- followup to the ARM EFI entry code simplifications to ensure that we
  don't rely on EFI_LOADER_DATA memory being RWX
- fixes from Arvind to ensure that the new mixed mode approach works as
  expected regardless of where the image is loaded in memory by the UEFI
  PE/COFF loader
- more fixes from Arvind to make it more likely that the image can be
  decompressed in place, regardless of where it was loaded in memory
- efivars bugfix and some cleanup from Vladis
- incorporate a stable branch with the EFI pieces of Hans's work on
  loading device firmware from EFI boot service memory regions
- some followup fixes for the EFI stub changes that are queued for
  v5.7 already
- an endianness fix for the EFI GPT partition table driver
