Merge branch 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 EFI changes from Ingo Molnar: "Main changes: - Add support for earlyprintk=efi which uses the EFI framebuffer. Very useful for debugging boot problems. - EFI stub support for large memory maps (more than 128 entries) - EFI ARM support - this was mostly done by generalizing x86 <-> ARM platform differences, such as by moving x86 EFI code into drivers/firmware/efi/ and sharing it with ARM. - Documentation updates - misc fixes" * 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits) x86/efi: Add EFI framebuffer earlyprintk support boot, efi: Remove redundant memset() x86/efi: Fix config_table_type array termination x86 efi: bugfix interrupt disabling sequence x86: EFI stub support for large memory maps efi: resolve warnings found on ARM compile efi: Fix types in EFI calls to match EFI function definitions. efi: Renames in handle_cmdline_files() to complete generalization. efi: Generalize handle_ramdisks() and rename to handle_cmdline_files(). efi: Allow efi_free() to be called with size of 0 efi: use efi_get_memory_map() to get final map for x86 efi: generalize efi_get_memory_map() efi: Rename __get_map() to efi_get_memory_map() efi: Move unicode to ASCII conversion to shared function. efi: Generalize relocate_kernel() for use by other architectures. efi: Move relocate_kernel() to shared file. efi: Enforce minimum alignment of 1 page on allocations. efi: Rename memory allocation/free functions efi: Add system table pointer argument to shared functions. efi: Move common EFI stub code from x86 arch code to common location ...
