Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent
Pull EFI fixes from Matt Fleming: * Avoid garbage names in efivarfs due to buggy firmware by zeroing EFI variable name. (Ross Lagerwall) * Stop erroneously dropping upper 32 bits of boot command line pointer in EFI boot stub and stash them in ext_cmd_line_ptr. (Roy Franz) * Fix double-free bug in error handling code path of EFI runtime map code. (Dan Carpenter) Signed-off-by: Ingo Molnar <mingo@kernel.org>
