Subject: [GIT PULL] Block driver changes for 4.6-rc

Hi Linus,

This is the block driver pull request for this merge window. It sits on
top of for-4.6/core, that was just sent out.

With the amount of changes we ended up having after the merge window in
4.5, there's a non trivial amount of merging for this branch for NVMe.
Even with resolving them correctly, you need to know that NVMe requires
a symbol export (nvme_kill_queues()) in the merged result that doesn't
exist in either branch, its only needed when they are merged together.
I'm providing you two options here:

1) Pull for-4.6/drivers and do the merges yourself. This is the original
   branch.

2) Pull for-4.6/drivers-merged, which is the above branch, but with v4.5
   merged into it and the merges resolved cleanly.

Diffstat below shown for the regular branch, for-4.6/drivers. This pull
request contains:


- A set of fixes for lightnvm. One from Alan, fixing an overflow, and
  the rest from the usual suspects, Javier and Matias.

- A set of fixes for nbd from Markus and Dan, and a fixup from Arnd for
  correct usage of the signed 64-bit divider.

- A set of bug fixes for the Micron mtip32xx, from Asai.

- A fix for the brd discard handling from Bart.

- Update the maintainers entry for cciss, since that hardware has
  transferred ownership.

- 3 bug fixes for bcache from Eric Wheeler.

- Set of fixes for xen-blk{back,front} from Jan and Konrad.

- Removal of the cpqarray driver. It has been disabled in Kconfig since
  2013, and we were initially scheduled to remove it in 3.15.

- Various updates and fixes for NVMe, with the most important being:

        - Removal of the per-device NVMe thread, replacing that with a
          watchdog timer instead. From Christoph.

        - Exposing the namespace WWID through sysfs, from Keith.

        - Set of cleanups from Ming Lin.

        - Logging the controller device name instead of the underlying
          PCI device name, from Sagi.

        - And a bunch of fixes and optimizations from the usual suspects
          in this area.

Please pull!
