Hi Keir, we have pushed the initial PowerPC support to
http://xenbits.xensource.com/ext/xenppc-unstable-merge.hg ; it's ready
for you to pull into xen-unstable.hg when you're satisfied with it.

Unforunately Jimi and I are both going to be traveling a bit in the
upcoming days, but we will address comments as possible. Also, we will
be in Ottawa to discuss in person if everything hasn't been ironed out
by then.

There are just a couple changes outside of xen/arch/powerpc that need

        We're using x86/irq.c wholesale, and so need this extra PIC logic.

        PowerPC's page->count_info is a long, because atomic operations are
performed on it. There's no need to change its type for the other
architectures, but this printk needed to change.

        This is the data structure that Linux uses to pass arbitrarily sized
buffers to Xen, so it needs to be in public/ .
