3.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Semen Protsenko <[email protected]> commit 6a7519e81321343165f89abb8b616df186d3e57a upstream. "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.
