Pull MD updates from Shaohua Li:

- Add Partial Parity Log (ppl) feature found in Intel IMSM raid array
by Artur Paszkiewicz. This feature is another way to close RAID5
writehole. The Linux implementation is also available for normal
RAID5 array if specific superblock bit is set.

- A number of md-cluser fixes and enabling md-cluster array resize from
Guoqing Jiang

- A bunch of patches from Ming Lei and Neil Brown to rewrite MD bio
handling related code. Now MD doesn't directly access bio bvec,
bi_phys_segments and uses modern bio API for bio split.

- Improve RAID5 IO pattern to improve performance for hard disk based
RAID5/6 from me.

- Several patches from Song Liu to speed up raid5-cache recovery and
allow raid5 cache feature disabling in runtime.

- Fix a performance regression in raid1 resync from Xiao Ni.

- Other cleanup and fixes from various people.

md/raid1: Use a new variable to count flighting sync requests

In new barrier codes, raise_barrier waits if conf->nr_pending[idx] is not zero.
After all the conditions are true, the resync request can go on be handled. But
it adds conf->nr_pending[idx] again. The next resync request hit the same bucket
idx need to wait the resync request which is submitted before. The performance
of resync/recovery is degraded.
So we should use a new variable to count sync requests which are in flight.

I did a simple test:
1. Without the patch, create a raid1 with two disks. The resync speed:
Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await r_await w_await svctm %util
sdb 0.00 0.00 166.00 0.00 10.38 0.00 128.00 0.03 0.20 0.20 0.00 0.19 3.20

2. With the patch, the result is:
sdb 2214.00 0.00 766.00 0.00 185.69 0.00 496.46 2.80 3.66 3.66 0.00 1.03 79.10

md/raid1: simplify the splitting of requests.

raid1 currently splits requests in two different ways for
two different reasons.

First, bio_split() is used to ensure the bio fits within a
resync accounting region.
Second, multiple r1bios are allocated for each bio to handle
the possiblity of known bad blocks on some devices.

This can be simplified to just use bio_split() once, and not
use multiple r1bios.
We delay the split until we know a maximum bio size that can
be handled with a single r1bio, and then split the bio and
queue the remainder for later handling.

This avoids all loops inside raid1.c request handling. Just
a single read, or a single set of writes, is submitted to
lower-level devices for each bio that comes from
generic_make_request().

When the bio needs to be split, generic_make_request() will
do the necessary looping and call md_make_request() multiple
times.

raid1_make_request() no longer queues request for raid1 to handle,
so we can remove that branch from the 'if'.

This patch also creates a new private bio_set
(conf->bio_split) for splitting bios. Using fs_bio_set
is wrong, as it is meant to be used by filesystems, not
block devices. Using it inside md can lead to deadlocks
under high memory pressure.

Backmerge drm-next to get at all the good stuff in drm-misc. We need
that because:

- drm_connector_list_iter conversion for i915 needs the core patches.
- Maarten's patches to use the new atomic state iterators also need
the core patches.
- We need the new link status property to complete the DP retraining
work, merging through 2 branches wasn't a good idea and we had to
partially backtrack.
- Chris needs reservation_object_trylock and we want to roll out
kref_read everywhere.
