Hi kvm-devs,
  Been away from the kvm scene for a while...hope everyone is well.

FYI: There are a few build breakages between kvm-userspace.git HEAD
(f29d402ab885d30bfa7350378cff911c9c17a226) when you compile against
Linus' linux-2.6.git HEAD
(v2.6.29-rc8-041b62374c7fedc11a8a1eeda2868612d3d1436c)

I am not sure if this is a supported configuration (e.g. perhaps you
only support building kvm-userspace HEAD against Avi's kernel tree?). 
But in case this was unintentional, read on...

First error:

libkvm.c:702: error: ‘struct kvm_irq_level’ has no member named ‘status’
make[1]: *** [libkvm.o] Error 1

Which is attributable to:

commit ea1b668e7684dc43e9d198ba0b25fe47a0b2acd2
Author: Gleb Natapov <gleb@redhat.com>
Date:   Wed Feb 4 17:30:01 2009 +0200

    kvm: qemu: handle IRQ status injection in userspace
   
Reverting this patch does allow the build to get past this error.  Then
I hit the next one:

device-assignment.o: In function `deassign_device':
/home/ghaskins/sandbox/git/fabric/kvm-userspace/qemu/hw/device-assignment.c:562:
undefined reference to `kvm_deassign_pci_device'

Reverting:

commit 1435f18213edee9fabf936f5d6be70054f1f2bd1
Author: Weidong Han <weidong.han@intel.com>
Date:   Wed Feb 18 14:33:41 2009 +0800

    kvm: qemu: fix hot remove assigned device
   
 Followed by:

commit 71ae34caaa961330f53f40090cd180a74fcda5fc
Author: Weidong Han <weidong.han@intel.com>
Date:   Wed Feb 18 14:28:30 2009 +0800

    kvm: qemu: deassign device from guest
   
Does fix the build.  I realize reversion is probably not the desirable
long term solution, but at least it points to the proper places that
need some backwards-compat love ;)

Regards,
-Greg
