It would be, but my proposals to move the fields out in earlier patches
had been turned down by you. So, while I work on another solution, this
would help. It's on my list to work on. As soon as dom0 pvh patches
are in, I intend to work on fixmes. I don't understand very well whats
going on with pirq eoi, so need to study it both in xen and linux, 
and focussing on one thing at a time really helps mortals like me :) ... 

thanks,
Mukesh
