Subject: [KVM PATCH v4 0/3] iosignalfd

(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")
