Here are some changes for xenpaging in xen-unstable.
Patches 1 to 7 are likely non-controversial and could be applied.
All later patches need more review (8-11), and more work from my side (12+).
This series uses the recently added wait_event feature. The __hvm_copy
patch crashes Xen with what looks like stack corruption. After a few
populate/resume iterations. I have added some printk to the
populate/resume functions and also wait.c. This leads to crashes. It
rarely prints a clean backtrace like the one shown below (most of the
time a few cpus crash at once).
If I leave my debug patch out, then the console and also network is dead.
However, the remote power switch is able to inject some reboot event
into dom0. The shutdown scripts get up to the point where xend is
stopped. After a timeout the system is hard rebooted.
