efi: READ_ONCE rng seed size before munmap (2020-02-17 17:46:26 +0100)

EFI fixes for v5.6-rcX:
- some mixed mode fixes that came about after Hans reported issues in
the VA to PA translation code used by the mixed mode EFI runtime
service call wrappers.
- use READ_ONCE() to dereference the UEFI rng seed structure, which gets
mapped, unmapped and remapped without the compiler being aware of it.

Ard Biesheuvel (3):
efi/x86: align GUIDs to their size in the mixed mode runtime wrapper
efi/x86: remove support for EFI time and counter services in mixed mode
efi/x86: Handle by-ref arguments covering multiple pages in mixed mode

Jason A. Donenfeld (1):
efi: READ_ONCE rng seed size before munmap
