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)
