After changing the timing between GTT updates and execution on the GPU,
we started seeing sporadic failures on Ironlake. These were narrowed
down to being an insufficiently strong enough barrier/delay after
updating the GTT and scheduling execution on the GPU. By forcing the
uncached read, and adding the missing barrier for the singular
insert_page (relocation paths), the sporadic failures go away.
Fixes: 983d308cb8f6 ("agp/intel: Serialise after GTT updates")
Fixes: 3497971a71d8 ("agp/intel: Flush chipset writes after updating a single PTE")

With timeslice yielding on a semaphore, we may complete timeslices much
faster than we were expecting and already have yielded the stuck
request. Before complaining that timeslicing is not enabled, check that
we haven't already applied the switch.

With amdgpu and CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y, there are
errors like:
BUG: non-zero pgtables_bytes on freeing mm
and:
BUG: Bad rss-counter state
with TTM transparent huge-pages.
Until we've figured out what other TTM drivers do differently compared to
vmwgfx, disable the huge_fault() callback, eliminating transhuge
page-table entries.

Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

Pull ceph updates from Ilya Dryomov:
"The main items are:
- support for asynchronous create and unlink (Jeff Layton).
Creates and unlinks are satisfied locally, without waiting for a
reply from the MDS, provided the client has been granted
appropriate caps (new in v15.y.z ("Octopus") release). This can be
a big help for metadata heavy workloads such as tar and rsync.
Opt-in with the new nowsync mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself).
When the driver was converted to blk-mq, we settled on a single
blk-mq queue because of a global lock in libceph and some other
technical debt. These have since been addressed, so allocate a
queue per CPU to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan).
This has been our long-standing behavior, but it causes issues with
some active/standby applications (synchronous I/O, stalls if the
standby goes down, etc).
- .snap directory timestamps consistent with ceph-fuse (Luis
Henriques)"

Pull libnvdimm and dax updates from Dan Williams:
"There were multiple touches outside of drivers/nvdimm/ this round to
add cross arch compatibility to the devm_memremap_pages() interface,
enhance numa information for persistent memory ranges, and add a
zero_page_range() dax operation.
This cycle I switched from the patchwork api to Konstantin's b4 script
for collecting tags (from x86, PowerPC, filesystem, and device-mapper
folks), and everything looks to have gone ok there. This has all
appeared in -next with no reported issues.
Summary:
- Add support for region alignment configuration and enforcement to
fix compatibility across architectures and PowerPC page size
configurations.
- Introduce 'zero_page_range' as a dax operation. This facilitates
filesystem-dax operation without a block-device.
- Introduce phys_to_target_node() to facilitate drivers that want to
know resulting numa node if a given reserved address range was
onlined.
- Advertise a persistence-domain for of_pmem and papr_scm. The
persistence domain indicates where cpu-store cycles need to reach
in the platform-memory subsystem before the platform will consider
them power-fail protected.
- Promote numa_map_to_online_node() to a cross-kernel generic
facility.
- Save x86 numa information to allow for node-id lookups for reserved
memory ranges, deploy that capability for the e820-pmem driver.
- Pick up some miscellaneous minor fixes, that missed v5.6-final,
including a some smatch reports in the ioctl path and some unit
test compilation fixups.

CONFIG_AS_MOVNTDQA was introduced by commit 0b1de5d58e19 ("drm/i915:
Use SSE4.1 movntdqa to accelerate reads from WC memory").
We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.
Remove CONFIG_AS_MOVNTDQA, which is always defined.

This patch process phy compliance request by programming requested
vswing, pre-emphasis and test pattern.
v1: Initial patch.
v2: Fixes added during testing with test-scope. (Khaled/Clint/Manasi)
- pipe used as argument during registers programming instead of port.
- TRANS_CONF must be disable/enable as well during ddi disable/enable.
- harcoded PLTPAT 80 bit custom pattern as the DPR-100 does not set it
in the sink’s DPCDs
- TRANS_DDI_FUNC_CTL DDI_Select (Bits 27:30) need to reset/set during
disable/enable.
v3: used macros instead of numbers and some cosmetic changes. [Manasi]

DP_COMP_CTL and DP_COMP_PAT register used to program DP
compliance pattern.
v1: Initial patch.
v2: used pipe instead of port in macro definition. [Manasi]
v3: used trans_offset for offset calculation. [Manasi]
v4: Used MMIO_PIPE for evenly spaced register offset instead
MMIO_PIPE2. [Ville]

vswing/pre-emphasis adjustment calculation is needed in processing
of auto phy compliance request other than link training, so have
made non-static function.
No functional change.
v1: initial patch.
v2:
- used "intel_dp" prefix in function name. (Jani)
- used array notation instead pointer for link_status. (Ville)
v3: Scrapped the initial patch, modified commit description accordingly.
- made non-static function and used intel_dp prefix. (Jani, Manasi)

During phy compliance auto test mode source need to read
requested test pattern from sink through DPCD. After processing
the request source need to set the pattern. So set/get method
added in drm layer as it is DP protocol.
v2: As per review feedback from Manasi on RFC version,
- added dp revision as function argument in set_phy_pattern api.
- used int for link_rate and u8 for lane_count to align with existing code.
v3: As per review feedback from Harry,
- used sizeof() instead of magic number.
- corrected kernel-doc for drm_dp_phy_test_params structure.
