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.
