Subject: [PATCH] don't assume iosapic interrupt controllers

Some ia64 machines don't use an iosapic interrupt controller (a flagrant
violation of the DIG64 spec, gasp!), so don't assume it's there in
mca.c.  This patch got no complaints last time I posted it, so I'm
proposing it for inclusion.

Thanks,
Jesse
