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.

efi/printf: Refactor code to consolidate padding and output

Consolidate the actual output of the formatted text into one place.

Fix a couple of edge cases:
1. If 0 is printed with a precision of 0, the printf specification says
that nothing should be output, with one exception (2b).
2. The specification for octal alternate format (%#o) adds the leading
zero not as a prefix as the 0x for hexadecimal is, but by increasing
the precision if necessary to add the zero. This means that
a. %#.2o turns 8 into "010", but 1 into "01" rather than "001".
b. %#.o prints 0 as "0" rather than "", unlike the situation for
decimal, hexadecimal and regular octal format, which all output an
empty string.

Reduce the space allocated for printing a number to the maximum actually
required (22 bytes for a 64-bit number in octal), instead of the 66
bytes previously allocated.
