Merge branch 'x86-efi-kexec-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 EFI changes from Ingo Molnar: "This consists of two main parts: - New static EFI runtime services virtual mapping layout which is groundwork for kexec support on EFI (Borislav Petkov) - EFI kexec support itself (Dave Young)" * 'x86-efi-kexec-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (24 commits) x86/efi: parse_efi_setup() build fix x86: ksysfs.c build fix x86/efi: Delete superfluous global variables x86: Reserve setup_data ranges late after parsing memmap cmdline x86: Export x86 boot_params to sysfs x86: Add xloadflags bit for EFI runtime support on kexec x86/efi: Pass necessary EFI data for kexec via setup_data efi: Export EFI runtime memory mapping to sysfs efi: Export more EFI table variables to sysfs x86/efi: Cleanup efi_enter_virtual_mode() function x86/efi: Fix off-by-one bug in EFI Boot Services reservation x86/efi: Add a wrapper function efi_map_region_fixed() x86/efi: Remove unused variables in __map_region() x86/efi: Check krealloc return value x86/efi: Runtime services virtual mapping x86/mm/cpa: Map in an arbitrary pgd x86/mm/pageattr: Add last levels of error path x86/mm/pageattr: Add a PUD error unwinding path x86/mm/pageattr: Add a PTE pagetable populating function x86/mm/pageattr: Add a PMD pagetable populating function ...
