Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent
Pull EFI bug fixes from Matt Fleming:
* Fix bugs in our code that converts ucs2 strings to utf8 where we
unintentionally drop bits from the original string (Jason Andryuk)
* Add the efi-pstore variables to the variable whitelist so that
users can continue to delete them via efivarfs without needing to
manipulate the immutable flag (Matt Fleming)
