Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Ingo Molnar:
"Main changes in this cycle were:
- Refactor the EFI memory map code into architecture neutral files
and allow drivers to permanently reserve EFI boot services regions
on x86, as well as ARM/arm64. (Matt Fleming)
- Add ARM support for the EFI ESRT driver. (Ard Biesheuvel)
- Make the EFI runtime services and efivar API interruptible by
swapping spinlocks for semaphores. (Sylvain Chouleur)
- Provide the EFI identity mapping for kexec which allows kexec to
work on SGI/UV platforms with requiring the "noefi" kernel command
line parameter. (Alex Thorlton)
- Add debugfs node to dump EFI page tables on arm64. (Ard Biesheuvel)
- Merge the EFI test driver being carried out of tree until now in
the FWTS project. (Ivan Hu)
- Expand the list of flags for classifying EFI regions as "RAM" on
arm64 so we align with the UEFI spec. (Ard Biesheuvel)
- Optimise out the EFI mixed mode if it's unsupported (CONFIG_X86_32)
or disabled (CONFIG_EFI_MIXED=n) and switch the early EFI boot
services function table for direct calls, alleviating us from
having to maintain the custom function table. (Lukas Wunner)
- Miscellaneous cleanups and fixes"
