NVMe driver updates for 3.16

Hi Linus,

Mostly bugfixes again for the NVMe driver. I'd like to call out the exported tracepoint in the block layer; I believe Keith has cleared this with Jens. We've had a few reports from people who're really pounding on NVMe devices at scale, hence the timeout changes (and new module parameters), hotplug cpu deadlock, tracepoints, and minor performance tweaks.

The following changes since commit 89ca3b881987f5a4be4c5dbaa7f0df12bbdde2fd:

Linux 3.15-rc4 (2014-05-04 18:14:42 -0700)

I believe he has not, I haven't seen that patch before (otherwise it should have had an ack). But it's not deal, we just have to remember to undo it when the blk-mq conversion goes in.
