[PULL REQUEST] NVMe driver updates for 3.16

[PULL REQUEST] NVMe driver updates for 3.16

[Matthew Wilcox]

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.
