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:
"EFI loader robustness enhancements plus smaller fixes"
* 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
efi: Fix the ACPI BGRT driver for images located in EFI boot services memory
efi: Add a function to look up existing IO memory mappings
efi: Defer freeing boot services memory until after ACPI init
x86, EFI: Calculate the EFI framebuffer size instead of trusting the firmware
efifb: Skip DMI checks if the bootloader knows what it's doing
efi: initialize efi.runtime_version to make query_variable_info/update_capsule workable
efi: Build EFI stub with EFI-appropriate options
X86: Improve GOP detection in the EFI boot stub
