Subject: xen-paravirt_ops: fix patch site clobbers to include return register
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
Fix a few clobbers to include the return register. The clobbers set is the
set of all registers modified (or may be modified) by the code snippet,
regardless of whether it was deliberate or accidental.
