Subject: [KVM PATCH v5 0/2] iosignalfd

(Applies to kvm.git/master:25deed73)

This is v5 of the series.  For more details, please see the header to
patch 2/2.

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:

      v5:
           *) Removed "cookie" field, which was a misunderstanding on my
              part on what Avi wanted for a data-match feature
	   *) Added a new "trigger" data-match feature which I think is
              much closer to what we need.
	   *) We retain the dev_count field in the io_bus infrastructure
	      and instead back-fill the array on removal.
	   *) Various minor cleanups
	   *) Rebased to kvm.git/master:25deed73

      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")
