Merge tag 'for-4.11/linus-merge-signed' of git://git.kernel.dk/linux-block

Pull block layer updates from Jens Axboe:

- blk-mq scheduling framework from me and Omar, with a port of the
deadline scheduler for this framework. A port of BFQ from Paolo is in
the works, and should be ready for 4.12.

- Various fixups and improvements to the above scheduling framework
from Omar, Paolo, Bart, me, others.

- Cleanup of the exported sysfs blk-mq data into debugfs, from Omar.
This allows us to export more information that helps debug hangs or
performance issues, without cluttering or abusing the sysfs API.

- Fixes for the sbitmap code, the scalable bitmap code that was
migrated from blk-mq, from Omar.

- Removal of the BLOCK_PC support in struct request, and refactoring of
carrying SCSI payloads in the block layer. This cleans up the code
nicely, and enables us to kill the SCSI specific parts of struct
request, shrinking it down nicely. From Christoph mainly, with help
from Hannes.

- Support for ranged discard requests and discard merging, also from
Christoph.

- Support for OPAL in the block layer, and for NVMe as well. Mainly
from Scott Bauer, with fixes/updates from various others folks.

- Error code fixup for gdrom from Christophe.

- cciss pci irq allocation cleanup from Christoph.

- Making the cdrom device operations read only, from Kees Cook.

- Fixes for duplicate bdi registrations and bdi/queue life time
problems from Jan and Dan.

- Set of fixes and updates for lightnvm, from Matias and Javier.

- A few fixes for nbd from Josef, using idr to name devices and a
workqueue deadlock fix on receive. Also marks Josef as the current
maintainer of nbd.

- Fix from Josef, overwriting queue settings when the number of
hardware queues is updated for a blk-mq device.

- NVMe fix from Keith, ensuring that we don't repeatedly mark and IO
aborted, if we didn't end up aborting it.

- SG gap merging fix from Ming Lei for block.

- Loop fix also from Ming, fixing a race and crash between setting loop
status and IO.

- Two block race fixes from Tahsin, fixing request list iteration and
fixing a race between device registration and udev device add
notifiations.

- Double free fix from cgroup writeback, from Tejun.

- Another double free fix in blkcg, from Hou Tao.

- Partition overflow fix for EFI from Alden Tondettar.

blk-mq-sched: add framework for MQ capable IO schedulers

This adds a set of hooks that intercepts the blk-mq path of
allocating/inserting/issuing/completing requests, allowing
us to develop a scheduler within that framework.

We reuse the existing elevator scheduler API on the registration
side, but augment that with the scheduler flagging support for
the blk-mq interfce, and with a separate set of ops hooks for MQ
devices.

We split driver and scheduler tags, so we can run the scheduling
independently of device queue depth.

ASoC: Fixes for v4.4

Quite a large batch of fixes have come in since the merge window, mainly
driver specific ones but there's a couple of core ones:

- A fix for DAPM resume on active streams to ensure everything ends up
cleanly in the right state.
- Reset the DAPM cache when freeing widgets to fix a crash on driver
remove and reload.

The PM functions for nau8825 are new code which fix crashes on resume.
