Merge tag 'efi-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI changes from Ingo Molnar: - Preliminary RISC-V enablement - the bulk of it will arrive via the RISCV tree. - Relax decompressed image placement rules for 32-bit ARM - Add support for passing MOK certificate table contents via a config table rather than a EFI variable. - Add support for 18 bit DIMM row IDs in the CPER records. - Work around broken Dell firmware that passes the entire Boot#### variable contents as the command line - Add definition of the EFI_MEMORY_CPU_CRYPTO memory attribute so we can identify it in the memory map listings. - Don't abort the boot on arm64 if the EFI RNG protocol is available but returns with an error - Replace slashes with exclamation marks in efivarfs file names - Split efi-pstore from the deprecated efivars sysfs code, so we can disable the latter on !x86. - Misc fixes, cleanups and updates. * tag 'efi-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits) efi: mokvar: add missing include of asm/early_ioremap.h efi: efivars: limit availability to X86 builds efi: remove some false dependencies on CONFIG_EFI_VARS efi: gsmi: fix false dependency on CONFIG_EFI_VARS efi: efivars: un-export efivars_sysfs_init() efi: pstore: move workqueue handling out of efivars efi: pstore: disentangle from deprecated efivars module efi: mokvar-table: fix some issues in new code efi/arm64: libstub: Deal gracefully with EFI_RNG_PROTOCOL failure efivarfs: Replace invalid slashes with exclamation marks in dentries. efi: Delete deprecated parameter comments efi/libstub: Fix missing-prototypes in string.c efi: Add definition of EFI_MEMORY_CPU_CRYPTO and ability to report it cper,edac,efi: Memory Error Record: bank group/address and chip id edac,ghes,cper: Add Row Extension to Memory Error Record efi/x86: Add a quirk to support command line arguments on Dell EFI firmware efi/libstub: Add efi_warn and *_once logging helpers integrity: Load certs from the EFI MOK config table integrity: Move import of MokListRT certs to a separate routine efi: Support for MOK variable config table ...
