[GIT PULL] lightnvm support

[GIT PULL] lightnvm support

[Jens Axboe]

Hi Linus,

First of the topic branches, these are on top of core+drivers. This
first one adds support for lightnvm, and adds support to NVMe as well.
This is pretty exciting, in that it enables new and interesting use
cases for compatible flash devices. There's a LWN writeup about an
earlier posting here:

This has been underway for a while, and should be ready for merging at
this point. Please pull!
