From: Ard Biesheuvel <ardb@kernel.org>

v3:
- add patch to make the SMBIOS protocol glue code compatible with mixed
mode on x86
- update Aditya's patch to limit the effect to dual GPU Macs that are
known to require the set_os() calls in order for both GPUs to remain
active after boot
- drop mixed mode handling of set_os() protocol, and dereference the
struct members directly
