Folks, here's the queue of EFI material for v4.7. This is probably the
biggest EFI pull ever sent, and there quite a few different topics
covered.
On the plus side the majority of new features (EFI Memory Attribute
tables, EFI capsules, GOP framebuffer) are basically architecture
independent, and some of the existing architecture-specific code has
been generalised and moved to drivers/firmware/efi.
The following changes since commit c3b46c73264b03000d1e18b22f5caf63332547c9:
Linux 4.6-rc4 (2016-04-17 19:13:32 -0700)

efi/runtime-wrappers: Remove ARCH_EFI_IRQ_FLAGS_MASK ifdef (2016-04-25 16:53:59 +0100)
----------------------------------------------------------------
* Drop the unused EFI_SYSTEM_TABLES efi.flags bit and ensure the
ARM/arm64 EFI System Table mapping is read-only - Ard Biesheuvel
* Add a comment to explain that one of the code paths in the x86/pat
code is only executed for EFI boot - Matt Fleming
* Improve Secure Boot status checks on arm64 and handle unexpected
errors - Linn Crosetto
* Remove the global EFI memory map variable 'memmap' as the same
information is already available in efi::memmap - Matt Fleming
* EFI Memory Attribute table support for ARM/arm64 - Ard Biesheuvel
* EFI GOP framebuffer support for ARM/arm64 - Ard Biesheuvel
* EFI Bootloader Control driver for storing reboot(2) data in EFI
variables for consumption by bootloaders - Jeremy Compostella
* Core EFI capsule support - Matt Fleming
* EFI capsule char driver - Kweh, Hock Leong
* EFI memory map code unification for ARM and arm64 - Ard Biesheuvel
* Add generic EFI support for detecting when firmware corrupts cpu
status register bits (like IRQ flags) when performing EFI runtime
service calls - Mark Rutland
----------------------------------------------------------------
Ard Biesheuvel (19):
efi: Get rid of EFI_SYSTEM_TABLES status bit
efi/arm*: Drop writable mapping of the UEFI System table
efi: Check EFI_MEMORY_DESCRIPTOR version explicitly
efi/arm*: Use memremap() to create the persistent memmap mapping
ARM: efi: Apply strict permissons for UEFI Runtime Services regions
arm64: efi: Apply strict permissons for UEFI Runtime Services regions
efi: Add support for the EFI_MEMORY_ATTRIBUTES_TABLE config table
efi: Implement generic support for the Memory Attributes table
efi/arm*: Take the Memory Attributes table into account
x86/efi: Prepare GOP handling code for reuse as generic code
efi/libstub: Move Graphics Output Protocol handling to generic code

efifb: Use builtin_platform_driver and drop unused includes
arm64/efi: libstub: Make screen_info accessible to the UEFI stub
efi/arm: libstub: Make screen_info accessible to the UEFI stub
efi/arm*: libstub: Wire up GOP protocol to struct screen_info
efi/arm*: Wire up struct screen_info to efi-framebuffer platform device
efifb: Enable the efi-framebuffer platform driver for ARM and arm64
efi/arm-init: Reserve rather than unmap the memory map for ARM as well
