Subject: [PATCH 1/5] x86: Fix .size directive for xen_do_hypervisor_callback

From: H.J. Lu <hjl.tools@...il.com>

[bwh: This is my summary.]

gas used to accept (and ignore?) .size directives which referred to
undefined symbols, as this does.  In binutils 2.21 these are treated
as errors.

If this is already headed to Linus by some other route, sorry for the
dupe.

HJL: Care to add your S-o-b?  (I can't believe this is even subject to
copyright, so I'm signing it off myself anyway.)

Ben.
