Move the last used path to the end of the list (least preferred) so that
ties are more evenly distributed.
For example, in case with three paths with one that is slower than
others, the remaining two would be unevenly used if they tie. This is
due to the rotation not being a truely fair distribution.
Illustrated: paths a, b, c, 'c' has 1 outstanding IO, a and b are 'tied'
Three possible rotations:
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
...
So 'a' is used 2x more than 'b', although they should be used evenly.
With this change, the most recently used path is always the least
preferred, removing this bias resulting in even distribution.
(a, b, c) -> best path 'a'
(b, c, a) -> best path 'b'
(c, a, b) -> best path 'a'
(c, b, a) -> best path 'b'

Since the unstripe target takes a target length which is the
size of *one* striped member we're trying to expose, not the
total size of *all* the striped members, the check does not
make sense and fails for some striped setups.
For example, say we have a 4TB striped device:
or 3907018496 sectors per underlying device:
if (sector_div(width, uc->stripes)) :
3907018496 / 2(num stripes) == 1953509248
tmp_len = width;
if (sector_div(tmp_len, uc->chunk_size)) :
1953509248 / 256(chunk size) == 7630895.5
(fails)
Fix this by removing the first check which isn't valid for unstriping.

The 'verify_rq_based:' code in dm_table_determine_type() was checking
all devices in the DM table rather than only checking the data devices.
Fix this by using the immutable target's iterate_devices method.
Also, tweak the block of dm_table_determine_type() code that decides
whether to upgrade from DM_TYPE_BIO_BASED to DM_TYPE_NVME_BIO_BASED so
that it makes sure the immutable_target doesn't support require
splitting IOs.
These changes have been verified to allow a "thin-pool" target whose
data device is an NVMe device to be upgraded to DM_TYPE_NVME_BIO_BASED.
Using the thin-pool in NVMe bio-based mode was verified to pass all the
device-mapper-test-suite's "thin-provisioning" tests.
Also verified that request-based DM multipath (with queue_mode "rq" and
"mq") works as expected using the 'mptest' harness.

Add DM_ENDIO_DELAY_REQUEUE to allow request-based multipath's
multipath_end_io() to instruct dm-rq.c:dm_done() to delay a requeue.
This is beneficial to do if BLK_STS_RESOURCE is returned from the target
(because target is busy).
Relative to blk-mq: kick the hw queues via blk_mq_requeue_work(),
indirectly from dm-rq.c:__dm_mq_kick_requeue_list(), after a delay.
For old .request_fn: use blk_delay_queue().
bio-based multipath doesn't have feature parity with request-based for
retryable error requeues; that is something that'll need fixing in the
future.

The Only use of PCI device enumeration here is to get the PMC base address
which is a fixed value i.e. 0xFE000000. On some platforms this can be read
through a non standard PCI BAR. But after Kabylake, PMC is not exposed as a
PCI device anymore. There are other non standard methods like ACPI LPIT
which can also be used for obtaining this value.
For simplicity, this value can be hardcoded as it won't change.
Since we don't have a PMC PCI device on any platform after Kabylake, this
creates a foundation for future SoC support.

When on a platform if we can't show MPHY and PLL status, don't even bother
to create a debugfs entry as it will fail anyway. In fact unless OEM builds
a special BIOS for test, it will fail on every production system.
This will help to add future platform support where we can't support these

Pull power management updates from Rafael Wysocki:
"This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend and
hibernation, plus some driver changes depending on them and fixes for
issues in that area which have become quite apparent recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on
Surface Pro3.
On the cpufreq front we have fixes and cleanups in the core, some new
hardware support, driver updates and the removal of some unused code
from the CPU cooling thermal driver.
Apart from this, the Operating Performance Points (OPP) framework is
prepared to be used with power domains in the future and there is a
usual bunch of assorted fixes and cleanups.
Specifics:
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver PM
flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of genpd
(Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the ACPI
core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal and
clean up the governor management code in the cpufreq core (Rafael
Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh
Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri
Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id from
the PSCI driver and drop dependency on arm_big_little from the SCPI
cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,
Kyungsik Lee).
- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy
Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
Sergey Senozhatsky, gaurav jindal).
- Make it easier to disable PM via Kconfig (Mark Brown).
- Clean up the cpupower and intel_pstate_tracer utilities (Doug
Smythies, Laura Abbott)"

to module name
It was found that ethtool provides unexisting module name while
it queries the specified network device for associated driver
information. Then user tries to unload that module by provided
module name and fails.
This happens because ethtool reads value of DRV_NAME macro,
while module name is defined at the driver's Makefile.
This patch is to correct Cavium CN88xx Thunder NIC driver names

We use 32bit bitmasks to track planes/crtcs/encoders/connectors.
Naturally we can only do that if the index of those objects stays
below 32. Issue a warning whenever we exceed that limit, hopefully
prompting someone to fix the problem.
For connectors the issue is a bit more complicated as they can
be created/destroyed at runtime due to MST. So the problem is no
longer a purely theoretical programmer error. As the connector
indexes are allocated via ida, we can simply limit the maximum
value the ida is allowed to hand out. The error handling is already
in place.

NULLed out, triggering an assert in rbd_obj_request_put():
rbd_img_request_put(parent_request)
rbd_parent_request_destroy
rbd_obj_request_put(NULL)
Just remove it -- parent_request->obj_request will be put in

Due to the way the composition is done in hardware, we can only have a
single alpha-enabled plane active at a time, placed in the second (highest
priority) pipe.
Make sure of that in our atomic_check to not end up in an impossible
scenario.

Our various planes have a configurable zpos, that combined with the pipes
allow to configure the composition.
Since the interaction between the pipes, zpos and alphas framebuffers is
not trivial, let's just enable the zpos as an immutable property for now,
and use that zpos in our atomic_update part.

The plane state zpos value will be set only if there's an existing state
attached to the plane when creating the property.
However, this is not the case during the probe, and we therefore need to
put our default value in our reset hook.

When a packet discontinuity happens, it is not just the payload
that was lost. The headers are lost too. So, the max size is not
184 but, instead 188.
Also, while printing warnings, make a distinction between
MPEG-TS indicated discontinuity and detected one.

There is a difference between the panel/bridge requested pixel clock
value and the real one due to the hw platform clock preciseness (pll,
dividers...). This patch updates the adjusted_mode clock value with
the real hw clock value so then attached encoder & connector can use
it for precise timing computations.
