Merge tag 'efi-fixes-for-v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI fixes from Ard Biesheuvel: - A pair of tweaks to the EFI random seed code so that externally provided version of this config table are handled more robustly - Another fix for the v6.0 EFI variable refactor that turned out to break Apple machines which don't provide QueryVariableInfo() - Add some guard rails to the EFI runtime service call wrapper so we can recover from synchronous exceptions caused by firmware * tag 'efi-fixes-for-v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: arm64: efi: Recover from synchronous exceptions occurring in firmware efi: efivars: Fix variable writes with unsupported query_variable_store() efi: random: Use 'ACPI reclaim' memory for random seed efi: random: reduce seed size to 32 bytes efi/tpm: Pass correct address to memblock_reserve
