Subject[GIT PULL] NVM Express driver

Hi Linus,

Please can you pull the NVM Express driver?

The only code touched outside the driver is adding an EXPORT_SYMBOL for
xen_biovec_phys_mergeable which was approved by Jens here:

The following changes since commit ccb19d263fd1c9e34948e2158c53eacbff369344:

Merge git:// (2012-01-17 22:26:41 -0800)

git:// master
