Merge tag 'efi_updates_for_v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Borislav Petkov:
"These got delayed due to a last minute ia64 build issue which got
fixed in the meantime.
EFI updates collected by Ard Biesheuvel:
- Don't move BSS section around pointlessly in the x86 decompressor
- Refactor helper for discovering the EFI secure boot mode
- Wire up EFI secure boot to IMA for arm64
- Some fixes for the capsule loader
- Expose the RT_PROP table via the EFI test module
- Relax DT and kernel placement restrictions on ARM
with a few followup fixes:
- fix the build breakage on IA64 caused by recent capsule loader
changes
- suppress a type mismatch build warning in the expansion of
EFI_PHYS_ALIGN on ARM"
* tag 'efi_updates_for_v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
efi: arm: force use of unsigned type for EFI_PHYS_ALIGN
efi: ia64: disable the capsule loader
efi: stub: get rid of efi_get_max_fdt_addr()
efi/efi_test: read RuntimeServicesSupported
efi: arm: reduce minimum alignment of uncompressed kernel
