(Applies to kvm.git/master:74dfca0a)

This is v4 of the series. For more details, please see the header to
patch 3/3.

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

This series is ready to be considered for inclusion, pending any further
review comments.

[
Changelog:

v4:
*) Fixed a bug in the original 2/4 where the PIT failure case
would potentially leave the io_bus components registered.
*) Condensed the v3 2/4 and 3/4 into one patch (2/2) since
the patches became interdependent with the fix described above
*) Rebased to kvm.git/master:74dfca0a

v3:
*) fixed patch 2/4 to handle error cases instead of BUG_ON
*) implemented same HAVE_EVENTFD protection mechanism as
irqfd to prevent compilation errors on unsupported arches
*) completed testing
*) rebased to kvm.git/master:7391a6d5

v2:
*) added optional data-matching capability (via cookie field)
*) changed name from iofd to iosignalfd
*) added io_bus unregister function
*) implemented deassign feature

v1:
*) original release (integrated into irqfd v7 series as "iofd")
