Adjust the cq/qp mask based on the number of bar2 pages in a host page.
For user-mode rdma, the granularity of the BAR2 memory mapped to a user
rdma process during queue allocation must be based on the host page
size. The lld attributes udb_density and ucq_density are used to figure
out how many sge contexts are in a bar2 page. So the rdev->qpmask and
rdev->cqmask in iw_cxgb4 need to now be adjusted based on how many sge
bar2 pages are in a host page.
Otherwise the device fails to work on non 4k page size systems.

There is a new reset driver for the Broadcom STB reset controller and
the i.MX7 system reset controller driver is extended to support i.MX8MQ
as well. Finally, there is a new header with reset id constants for
the Meson G12A SoC, which has a reset controller identical to Meson AXG

Given a master fd we can then override the priority of the context
in another fd.
Using these overrides was recommended by Christian instead of trying
to submit from a master fd, and I am adding a way to override a
single context instead of the entire process so we can only upgrade
a single Vulkan queue and not effectively the entire process.
Reused the flags field as it was checked to be 0 anyways, so nothing
used it. This is source-incompatible (due to the name change), but
ABI compatible.

I don't see another way to figure out if a ring is initialized if
the hardware block might not be initialized.
Entities have been fixed up to handle num_rqs = 0.

Some blocks in amdgpu can have 0 rqs.
Job creation already fails with -ENOENT when entity->rq is NULL,
so jobs cannot be pushed. Without a rq there is no scheduler to
pop jobs, and rq selection already does the right thing with a
list of length 0.
So the operations we need to fix are:
- Creation, do not set rq to rq_list[0] if the list can have length 0.
- Do not flush any jobs when there is no rq.
- On entity destruction handle the rq = NULL case.
- on set_priority, do not try to change the rq if it is NULL.

Add driver for serial-connected Mediatek-based GNSS receivers.
These devices typically boot transmitting vendor specific NMEA output
sequences. The serial port bit rate is read from the device tree
"current-speed".
Note that the driver uses the generic GNSS serial implementation and
therefore essentially only manages power abstracted into three power
states: ACTIVE, STANDBY, and OFF.
For mediatek receivers with a main supply and no enable-gpios, this simply
means that the main supply is disabled in STANDBY and OFF (the optional
backup supply is kept enabled while the driver is bound).
Note that the timepulse-support is left unimplemented.

Drop PROVE_LOCKING as it should not be enabled in the defconfig. It
causes quite a bit overhead as noted in the patch description.
Then let's update omap2plus_defconfig for dropped options and moved
options. That way makesavedefconfig can actually be used to generate
patches against omap2plus_defconfig.

QUEUE_FLAG_NO_SG_MERGE has been killed, so kill BLK_MQ_F_SG_MERGE too.

Since bdced438ac ("block: setup bi_phys_segments after splitting"),
physical segment number is mainly figured out in blk_queue_split() for
fast path, and the flag of BIO_SEG_VALID is set there too.
Now only blk_recount_segments() and blk_recalc_rq_segments() use this
flag.
Basically blk_recount_segments() is bypassed in fast path given BIO_SEG_VALID
is set in blk_queue_split().
For another user of blk_recalc_rq_segments():
- run in partial completion branch of blk_update_request, which is an unusual case
- run in blk_cloned_rq_check_limits(), still not a big problem if the flag is killed
since dm-rq is the only user.
Multi-page bvec is enabled now, not doing S/G merging is rather pointless with the
current setup of the I/O path, as it isn't going to save you a significant amount
of cycles.

Now multi-page bvec can cover CONFIG_THP_SWAP, so we don't need to
increase BIO_MAX_PAGES for it.
CONFIG_THP_SWAP needs to split one THP into normal pages and adds
them all to one bio. With multipage-bvec, it just takes one bvec to
hold them all.

This patch introduces one extra iterator variable to bio_for_each_segment_all(),
then we can allow bio_for_each_segment_all() to iterate over multi-page bvec.
Given it is just one mechannical & simple change on all bio_for_each_segment_all()
users, this patch does tree-wide change in one single patch, so that we can
avoid to use a temporary helper for this conversion.

bch_bio_alloc_pages() is always called on one new bio, so it is safe
to access the bvec table directly. Given it is the only kind of this
case, open code the bvec table access since bio_for_each_segment_all()
will be changed to support for iterating over multipage bvec.

First it is more efficient to use bio_for_each_bvec() in both
blk_bio_segment_split() and __blk_recalc_rq_segments() to compute how
many multi-page bvecs there are in the bio.
Secondly once bio_for_each_bvec() is used, the bvec may need to be
splitted because its length can be very longer than max segment size,
so we have to split the big bvec into several segments.
Thirdly when splitting multi-page bvec into segments, the max segment
limit may be reached, so the bio split need to be considered under
this situation too.
