Subject: [GIT PULL 00/29] EFI changes for v4.9
Folks, please queue up the following patches for v4.9. There's more
work on refactoring EFI code to be architecture independent and the
largest number of patches is spent cleaning up the EFI memory map code
and allowing drivers on x86 to reserve EFI boot services for all of
runtime.
The architecture independent quest is going pretty well and it was
only a couple of lines to get the esrt driver working on arm64.
Other than that there's some cleanups and fixes, and a merge of the
out of tree EFI runtime driver from the FWTS project.
The following changes since commit c6935931c1894ff857616ff8549b61236a19148f:
Linux 4.8-rc5 (2016-09-04 14:31:46 -0700)

x86/efi: Allow invocation of arbitrary boot services (2016-09-09 16:08:57 +0100)
----------------------------------------------------------------
* 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
----------------------------------------------------------------
Alex Thorlton (1):
x86/efi: Map in physical addresses in efi_map_region_fixed

efi: Replace runtime services spinlock with semaphore
efi/arm64: Add debugfs node to dump UEFI runtime page tables

efi: Split out EFI memory map functions into new file
efi: Add efi_memmap_install() for installing new EFI memory maps
efi: Allow drivers to reserve boot services forever
efi/runtime-map: Use efi.memmap directly instead of a copy

x86/efi: Defer efi_esrt_init until after memblock_x86_fill
Sylvain Chouleur (2):
efi: Use a file local lock for efivars
efi: Don't use spinlocks for efi vars
