[GIT PULL] EFI updates for v5.19

[GIT PULL] EFI updates for v5.19

[Ard Biesheuvel]

Hi Linus,

Please pull the changes below. Note the conflict in drivers/virt/Kconfig and
Makefile: this is due to CoCo changes arriving via different trees, and the
resolution is obvious.

Thanks,
Ard.

  riscv/efi_stub: Add support for RISCV_EFI_BOOT_PROTOCOL (2022-05-19 10:22:17 +0200)

----------------------------------------------------------------
EFI updates for v5.19

- Allow runtime services to be re-enabled at boot on RT kernels.
- Provide access to secrets injected into the boot image by CoCo
  hypervisors (COnfidential COmputing)
- Use DXE services on x86 to make the boot image executable after
  relocation, if needed.
- Prefer mirrored memory for randomized allocations.
- Only randomize the placement of the kernel image on arm64 if the
  loader has not already done so.
- Add support for obtaining the boot hartid from EFI on RISC-V.
