Log Message:
reduce hypervisor stack use with -O2, this really fixes bug (#198932)

--- NEW FILE xen-build-with-O2.patch ---
Always build the hypervisor with -O2.  This reduces stack consumption
significantly and seems to stop the stack overflows that made Xen crash
frequently in some configurations.
