Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Ingo Molnar: "The main changes in this cycle were: - Transparently fall back to other poweroff method(s) if EFI poweroff fails (and returns) - Use separate PE/COFF section headers for the RX and RW parts of the ARM stub loader so that the firmware can use strict mapping permissions - Add support for requesting the firmware to wipe RAM at warm reboot - Increase the size of the random seed obtained from UEFI so CRNG fast init can complete earlier - Update the EFI framebuffer address if it points to a BAR that gets moved by the PCI resource allocation code - Enable "reset attack mitigation" of TPM environments: this is enabled if the kernel is configured with CONFIG_RESET_ATTACK_MITIGATION=y. - Clang related fixes - Misc cleanups, constification, refactoring, etc" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi/bgrt: Use efi_mem_type() efi: Move efi_mem_type() to common code efi/reboot: Make function pointer orig_pm_power_off static efi/random: Increase size of firmware supplied randomness efi/libstub: Enable reset attack mitigation firmware/efi/esrt: Constify attribute_group structures firmware/efi: Constify attribute_group structures firmware/dcdbas: Constify attribute_group structures arm/efi: Split zImage code and data into separate PE/COFF sections arm/efi: Replace open coded constants with symbolic ones arm/efi: Remove pointless dummy .reloc section arm/efi: Remove forbidden values from the PE/COFF header drivers/fbdev/efifb: Allow BAR to be moved instead of claiming it efi/reboot: Fall back to original power-off method if EFI_RESET_SHUTDOWN returns efi/arm/arm64: Add missing assignment of efi.config_table efi/libstub/arm64: Set -fpie when building the EFI stub efi/libstub/arm64: Force 'hidden' visibility for section markers efi/libstub/arm64: Use hidden attribute for struct screen_info reference efi/arm: Don't mark ACPI reclaim memory as MEMBLOCK_NOMAP
