Right, entry-xen.S has problems --- it's broken even with the
CONFIG_DEBUG_INFO disable, as setting the new CONFIG_UNWIND_INFO
option still breaks it again.  But that's just as easy to disable as a
temporary workaround.  (I'd still like to find out why CFI is breaking
on Xen with those options disabled, though.)
