alloc_workqueue replaces deprecated create_singlethread_workqueue().
Each hardware CRTC has a single flip work queue.
When a radeon_flip_work_func item is queued, it needs to be executed
ASAP because even a slight delay may cause the flip to be delayed by
one refresh cycle.
Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here
since a delay can cause the outcome to miss the refresh cycle.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.

Just about all of amdgpu's connector probing functions try to acquire
runtime PM refs. If we try to do this in the context of
amdgpu_resume_kms by calling drm_helper_hpd_irq_event(), we end up
deadlocking the system.
Since we're guaranteed to be holding the spinlock for RPM in
amdgpu_resume_kms, and we already know the GPU is in working order, we
need to prevent the RPM helpers from trying to run during the initial
connector reprobe on resume.
There's a couple of solutions I've explored for fixing this, but this
one by far seems to be the simplest and most reliable (plus I'm pretty
sure that's what disable_depth is there for anyway).
Reproduction recipe:
- Get any laptop dual GPUs using PRIME
- Make sure runtime PM is enabled for amdgpu
- Boot the machine
- If the machine managed to boot without hanging, switch out of X to
another VT. This should definitely cause X to hang infinitely.
Changes since v1:
- add appropriate #ifdef checks for CONFIG_PM. This is not very
useful, but it appears some kernel test suites test compiling amdgpu
with CONFIG_PM disabled, which results in this patch breaking the builds
if we don't include this #ifdef

The workqueue "workq" provides support for sd/mmc async request, which
makes next request do dma_map_sg() while previous request transferring
data.
The workqueue has a single workitem(&host->work) and hence doesn't require
ordering. Also, it is not being used on a memory reclaim path. Hence,
the singlethreaded workqueue has been replaced with the use of system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Work item has been flushed in rtsx_pci_sdmmc_drv_remove() to ensure that
there are no pending tasks while disconnecting the driver.

The rtsx_pci driver is using a fixed 3s timeout for R1B responses, which
in some cases isn't suffient. For example, erase/discard requests may
require longer timeouts.
Instead of always using a fixed timeout, let's use the per request
calculated busy timeout from the mmc core.

Move the system PM callbacks within #ifdef CONFIG_PM_SLEEP as to avoid
them being build when not used. This also allows us to use the

Within this context it also makes sense to move the declaration of the
struct sdhci_pltfm_pmops, outside the #ifdef CONFIG_PM as the
SET_SYSTEM_SLEEP_PM_OPS deals with this. This further simplifies the code.

version 8:
- move drm_blend.o from drm-y to drm_kms_helper-y to avoid
EXPORT_SYMBOL(drm_atomic_helper_normalize_zpos)
- remove dead function declarations in drm_crtc.h
version 7:
- remove useless EXPORT_SYMBOL()
- better z-order wording in Documentation
version 6:
- add zpos in gpu documentation file
- merge Ville patch about zpos initial value and API improvement.
I have split Ville patch between zpos core and drivers
version 5:
- remove zpos range check and comeback to 0 to N-1
normalization algorithm
version 4:
- make sure that normalized zpos value is stay
in the defined property range and warn user if not
This patch adds support for generic plane's zpos property property with
well-defined semantics:
- added zpos properties to plane and plane state structures
- added helpers for normalizing zpos properties of given set of planes
- well defined semantics: planes are sorted by zpos values and then plane
id value if zpos equals
Normalized zpos values are calculated automatically when generic
muttable zpos property has been initialized. Drivers can simply use
plane_state->normalized_zpos in their atomic_check and/or plane_update
callbacks without any additional calls to DRM core.

Pull libnvdimm updates from Dan Williams:
- Replace pcommit with ADR / directed-flushing.
The pcommit instruction, which has not shipped on any product, is
deprecated. Instead, the requirement is that platforms implement
either ADR, or provide one or more flush addresses per nvdimm.
ADR (Asynchronous DRAM Refresh) flushes data in posted write buffers
to the memory controller on a power-fail event.
Flush addresses are defined in ACPI 6.x as an NVDIMM Firmware
Interface Table (NFIT) sub-structure: "Flush Hint Address Structure".
A flush hint is an mmio address that when written and fenced assures
that all previous posted writes targeting a given dimm have been
flushed to media.
- On-demand ARS (address range scrub).
Linux uses the results of the ACPI ARS commands to track bad blocks
in pmem devices. When latent errors are detected we re-scrub the
media to refresh the bad block list, userspace can also request a
re-scrub at any time.
- Support for the Microsoft DSM (device specific method) command
format.
- Support for EDK2/OVMF virtual disk device memory ranges.
- Various fixes and cleanups across the subsystem.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.8 kernel cycle.
Nothing stands out as especially exiting: new drivers, new subdrivers,
lots of cleanups and incremental features.
Business as usual.
New drivers:
- New driver for Oxnas pin control and GPIO. This ARM-based chipset
is used in a few storage (NAS) type devices.
- New driver for the MAX77620/MAX20024 pin controller portions.
- New driver for the Intel Merrifield pin controller.
New subdrivers:
- New subdriver for the Qualcomm MDM9615
- New subdriver for the STM32F746 MCU
- New subdriver for the Broadcom NSP SoC.
Cleanups:
- Demodularization of bool compiled-in drivers.
Apart from this there is just regular incremental improvements to a
lot of drivers, especially Uniphier and PFC"
