Linus Torvalds e6f39a90de EFI fixes for v6.8 #1

- Tighten ELF relocation checks on the RISC-V EFI stub
 - Give up if the new EFI memory attributes protocol fails spuriously on
   x86
 - Take care not to place the kernel in the lowest 16 MB of DRAM on x86
 - Omit special purpose EFI memory from memblock
 - Some fixes for the CXL CPER reporting code
 - Make the PE/COFF layout of mixed-mode capable images comply with a
   strict interpretation of the spec

Pull EFI fixes from Ard Biesheuvel:
 "The only notable change here is the patch that changes the way we deal
  with spurious errors from the EFI memory attribute protocol. This will
  be backported to v6.6, and is intended to ensure that we will not
  paint ourselves into a corner when we tighten this further in order to
  comply with MS requirements on signed EFI code.

  Note that this protocol does not currently exist in x86 production
  systems in the field, only in Microsoft's fork of OVMF, but it will be
  mandatory for Windows logo certification for x86 PCs in the future.
