Merge tag 'efi-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into core/efi
Pull EFI updates from Matt Fleming:
- Fixes and cleanups for SMBIOS 3.0 DMI code. (Ivan Khoronzhuk)
- A new efi=debug command line option that enables debug output in the
EFI boot stub and results in less verbose EFI memory map output by
default. (Borislav Petkov)
- Disable interrupts around EFI calls and use a more standard page
table saving and restoring idiom when making EFI calls. (Ingo Molnar)
- Reduce the number of memory allocations performed when allocating the
FDT in EFI boot stub by retrieving size from the FDT header in the
EFI config table. (Ard Biesheuvel)
