3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Garrett <mjg@redhat.com>
commit 9dead5bbb825d7c25c0400e61de83075046322d0 upstream.
We can't assume the presence of the red zone while we're still in a boot services environment, so we should build with -fno-red-zone to avoid problems. Change the size of wchar at the same time to make string handling simpler.
