Hi Jens,

I'd like to get these merged during the v3.15 merge window.  I'd be glad to
review and apply them through my tree, unless you want to do it.  They do
depend on f7fc32c, which went in after the v3.14 merge window, which makes
it a bit of a hassle.

So let me know if you'd rather handle these; otherwise I'll review them and
put them in my tree next week.

I'll include the nvme update, since it has Keith's "Reviewed-by".

Bjorn
