[KVM PATCH v5 0/4] irqfd fixes and enhancements

[Gregory Haskins]

(Applies to kvm.git/master:4631e094)

The following is the latest attempt to fix the races in irqfd/eventfd, as
well as restore DEASSIGN support.  For more details, please read the patch
headers.

This series has been tested against the kvm-eventfd unit test, and
appears to be functioning properly.  You can download this test here:

ftp://ftp.novell.com/dev/ghaskins/kvm-eventfd.tar.bz2

I've included version 4 of Davide's eventfd patch (ported to kvm.git) so
that its a complete reviewable series.  Note, however, that there may be
later versions of his patch to consider for merging, so we should
coordinate with him.
