Merge branch 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 EFI updates from Ingo Molnar: "EFI changes: - Use idiomatic negative error values in efivar_create_sysfs_entry() instead of returning '1' to indicate error (Dan Carpenter) - Implement new support to expose the EFI System Resource Tables in sysfs, which provides information for performing firmware updates (Peter Jones) - Documentation cleanup in the EFI handover protocol section which falsely claimed that 'cmdline_size' needed to be filled out by the boot loader (Alex Smith) - Align the order of SMBIOS tables in /sys/firmware/efi/systab to match the way that we do things for ACPI and add documentation to Documentation/ABI (Jean Delvare)" * 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi: Work around ia64 build problem with ESRT driver efi: Add 'systab' information to Documentation/ABI efi: dmi: List SMBIOS3 table before SMBIOS table efi/esrt: Fix some compiler warnings x86, doc: Remove cmdline_size from list of fields to be filled in for EFI handover efi: Add esrt support efi: efivar_create_sysfs_entry() should return negative error codes
