I hadn't asked for a mm merge for the hwpoison version because
it still needed some work. mce has been ready for some time for
merge, although of course as we do more testing we still
find occasional bugs that are getting fixed.

There was some work recently on fixing problems found in the
hwpoison code during further review (me with Fengguang Wu). 
I'm hoping to do a repost with all the fixes soon
and then it's a mm candidate and hopefully ready for merge really soon.

Also there was a lot of work (mostly by Ying Huang) on the
mce-test testsuite which is covering more and more code, 
but of course could always need more work too.

The 32bit unification is complete, but the x86 maintainers
haven't merged it yet.

Sure any review or additional testing is welcome.

I wanted to do full reposts this week anyways, so you
can start from there again.

Great. Thanks. Can I add your Reviewed-by tags then?
