Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin: "A couple of key fixes and a few less critical ones. The main ones are: - add a .bss section to the PE/COFF headers when building with EFI stub - invoke the correct paravirt magic when building the espfix page tables Unfortunately both of these areas also have at least one additional fix each still in thie pipeline, but which are not yet ready to push" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86: Remove unused variable "polling" x86/espfix/xen: Fix allocation of pages for paravirt page tables x86/efi: Include a .bss section within the PE/COFF headers efi: fdt: Do not report an error during boot if UEFI is not available efi/arm64: efistub: remove local copy of linux_banner
