From: Semen Protsenko <semen.protsenko@xxxxxxxxxx> "efi" global data structure contains "runtime_version" field which must be assigned in order to use it later in Runtime Services virtual calls (virt_efi_* functions). Before this patch "runtime_version" was unassigned (0), so each Runtime Service virtual call that checks revision would fail.
