  efi/x86: Don't remap text<->rodata gap read-only for mixed mode (2020-04-09 14:50:21 +0200)

----------------------------------------------------------------
EFI fixes for v5.7-rcX:
- a couple of mixed mode fixes for the changes made in v5.6
- a couple of fixes from Arvind to deal with buggy firmware that does not
  load the PE/COFF kernel image based on the description in the PE/COFF
  header, but simply copies it to memory
- add a clarification to the x86 boot protocol documentation regarding the
  previous issue
- reduce the stack footprint of the new file I/O code, to suppress a
  compiler warning
- use the right sprintf() flavor in the CPER code to prevent a potential
  out of bounds write
- prevent a symbol reference from going out of range in the ARM startup code
- cosmetic fix for an issue reported by Coverity

----------------------------------------------------------------
Ard Biesheuvel (4):
      efi/arm: Deal with ADR going out of range in efi_enter_kernel()

      efi/libstub/file: merge filename buffers to reduce stack usage
      efi/x86: Don't remap text<->rodata gap read-only for mixed mode

Arvind Sankar (2):
      efi/x86: Move efi stub globals from .bss to .data
      efi/x86: Always relocate the kernel for EFI handover entry
