Could you please wait for a week or two before applying this patch
I am working on a different approach on interrupt remapping, basically
a replacement for patch 5, it also requires some modifications on the
xen side.
The basic idea is that from the kernel perspective asking event channel
delivery for real physical interrupts or event channel delivery for
emulated interrupts should be same thing. The code to do the former
is basically xen_setup_pirqs() in the pvops tree. I got it to work for
the first time a couple of days ago but it still needs to be polished
before I can send it to the list.
