Three of the patches could be squashed in one, but it makes more sense to review them as three. These patches fix the case of an PVHVM guest not being able to resume propely b/c of hitting: 142 BUG_ON(info->type != IRQT_UNBOUND && info->type != type); (in events.c) and also adds a WARN to catch situations like these. The reason for this is that the Xen python toolstack

I am working on some other bugs and perf issues - and while working I noticed that both sparse and Coverity have reported some issues with Xen drivers. Please see attached various bug-fixes that I am proposing for 3.6.

This patch series is fixing that issue by deferring the xenbus frontend resume when we are running xenstored in that same
