Log Message:
Various interrupt fixes, mainly:
keep a per-cpu mask of enabled events, and use it to get pending events.
A cpu-specific event (all of them at this time) should not be ever masked
by another CPU, because it may prevent the target CPU from seeing it
(the clock events all fires at once for example).

This patch breaks various xenstore/xenbus related functions, like ballooning. Steps to reproduce:
- connect to a dom0 system
- try ballooning up or down, with:
sysctl -w

All newly created processes will then stay in tstile, and the sysctl never returns, waiting on "rplq" wait channel.

Observed in QEMU, Virtualbox, and my amd64 spare host.
