Xen is probably going to be merged. I'm still not fully happy
about the review status of the drivers and xenbus, but there doesn't seem
to be much value in delaying it further.

I'll consolidate the fixes and fixes-to-fixes.


These all need re-review:

It's still not clear to me this is any useful. The current code
can run a program on MCE which should be really fast enough
for machine check handling.

I think that one was bogus.

Might need more testing?

I'm sceptical about the dynticks code. It just rips out the
x86-64 timing code completely, which needs a lot more review and testing.
Probably not .23
