Introduce EFI facilities, which informs users what EFI initialisation steps were completed successfully (are the system/config tables mapped, can we invoke runtime services, etc?) and allows users to clearly document which pieces of EFI firmware functionality they're using. The immediate motivation for this patch series is the bug report at, https://bugzilla.kernel.org/show_bug.cgi?id=47121 Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time.
