Merge tag 'x86_boot_for_v6.6_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 boot updates from Borislav Petkov:
 "Avoid the baremetal decompressor code when booting on an EFI machine.

  This is mandated by the current tightening of EFI executables
  requirements when used in a secure boot scenario. More specifically,
  an EFI executable cannot have a single section with RWX permissions,
  which conflicts with the in-place kernel decompression that is done
  today.

  Instead, the things required by the booting kernel image are done in
  the EFI stub now.

  Work by Ard Biesheuvel"
