3.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Semen Protsenko <semen.protse...@linaro.org>
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.
