Merge tag 'efi-next-for-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
- 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.
