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) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git tags/efi-next for you to fetch changes up to 4716a27d61ca3e3201d3201a6ee073da24902613: 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 x86/efi: efifb: Move DMI based quirks handling out of 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 Compostella, Jeremy (1): efibc: EFI Bootloader Control Kweh, Hock Leong (1): efi: A misc char interface to update EFI firmware Linn Crosetto (2): efi/arm64: Report unexpected errors when determining Secure Boot status efi/arm64: Check SetupMode when determining Secure Boot status Mark Rutland (10): efi/runtime-wrappers: Add {__,}efi_call_virt templates arm64/efi: Move to generic {__,}efi_call_virt arm/efi: Move to generic {__,}efi_call_virt x86/efi: Move to generic {__,}efi_call_virt efi/runtime-wrappers: Remove redundant ifdefs efi/runtime-wrappers: Detect firmware irq flag corruption arm64/efi: Enable runtime call flag checking arm/efi: Enable runtime call flag checking x86/efi: Enable runtime call flag checking efi/runtime-wrappers: Remove ARCH_EFI_IRQ_FLAGS_MASK ifdef Matt Fleming (7): x86/mm/pat: Document the (currently) EFI-only code path efi: Iterate over efi.memmap in for_each_efi_memory_desc efi: Remove global 'memmap' x86/efi: Remove the always true EFI_DEBUG symbol efi: Move efi_status_to_err() to drivers/firmware/efi/ efi: Capsule update support x86/efi: Force EFI reboot to process pending capsules arch/arm/include/asm/efi.h | 37 +-- arch/arm/kernel/efi.c | 41 +++ arch/arm/kernel/setup.c | 3 +- arch/arm64/include/asm/efi.h | 37 +-- arch/arm64/kernel/efi.c | 57 +++- arch/arm64/kernel/image.h | 1 + arch/ia64/kernel/efi.c | 2 -
