EFI still has two ways of exposing EFI variable to user space: the original sysfs interface and the efivarfs pseudo-filesystem that supersedes it, and which was introduced almost 10 years ago.
As a preparatory step towards refactoring the underlying infrastructure shared between efivarfs and efi-pstore, I would like to finally get rid of the sysfs interface which also uses that, but which is only enabled on x86 and Itanium.
