[GIT PULL] EFI changes for v4.21

   # HEAD: 1debf0958fa27b7c469dbf22754929ec59a7c0e7 x86/efi: Don't unmap EFI boot services code/data regions for EFI_OLD_MEMMAP and EFI_MIXED_MODE

The main changes in this cycle were:

  - Allocate the E820 buffer before doing the GetMemoryMap/ExitBootServices
    dance so we don't run out of space

  - Clear EFI boot services mappings when freeing the memory

  - Harden efivars against callers that invoke it on non-EFI boots 

  - Reduce the number of memblock reservations resulting from extensive
    use of the new efi_mem_reserve_persistent() API

  - Other assorted fixes and cleanups.

 Thanks,

	Ingo
