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 EFI changes in this cycle were: - Fix the apple-properties code (Andy Shevchenko) - Add WARN() on arm64 if UEFI Runtime Services corrupt the reserved x18 register (Ard Biesheuvel) - Use efi_switch_mm() on x86 instead of manipulating %cr3 directly (Sai Praneeth) - Fix early memremap leak in ESRT code (Ard Biesheuvel) - Switch to L"xxx" notation for wide string literals (Ard Biesheuvel) - ... plus misc other cleanups and bugfixes" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/efi: Use efi_switch_mm() rather than manually twiddling with %cr3 x86/efi: Replace efi_pgd with efi_mm.pgd efi: Use string literals for efi_char16_t variable initializers efi/esrt: Fix handling of early ESRT table mapping efi: Use efi_mm in x86 as well as ARM efi: Make const array 'apple' static efi/apple-properties: Use memremap() instead of ioremap() efi: Reorder pr_notice() with add_device_randomness() call x86/efi: Replace GFP_ATOMIC with GFP_KERNEL in efi_query_variable_store() efi/arm64: Check whether x18 is preserved by runtime services calls efi/arm*: Stop printing addresses of virtual mappings efi/apple-properties: Remove redundant attribute initialization from unmarshal_key_value_pairs() efi/arm*: Only register page tables when they exist
