e86ee2d44b ipmi: Rework locking and shutdown for hot remove
To handle hot remove of interfaces, a lot of rework had to be
done to the locking.  Several things were switched over to srcu
and shutdown for users and interfaces was added for cleaner
shutdown.

6aa2dd0092 ipmi_devintf: Small lock rework
The mutex didn't really serve any useful purpose, from what I can
tell, and it would just get in the way.  So remove it.

Removing that required a mutex around the default value setting and
getting, so just use the receive mutex for that.

Also pull the fasync stuff outside of the lock for adding the data
to the queue, since it didn't need to be there.

91e2dd0a47 ipmi: Add a panic handler for IPMI users
Users of the IPMI code had their own panic handlers, but the
order was not necessarily right, the base IPMI code would
need to handle the panic first, and the user had no way to
know if the IPMI interface could run at panic time.

Add a panic handler to the user interface, it is called if
non-NULL and the interface the user is on is capable of panic
handling.  It also cleans up the panic log handling a bit to
reuse the existing interface loop in the main panic handler.

d1b29b9742 ipmi:watchdog: Rework locking and handling
Simplify things by creating one set of message handling data for
setting the watchdog and doing a heartbeat.  Rework the locking
to avoid some (probably not very important) races and to avoid
a fairly unlikely infinite recursion.

Get rid of ipmi_ignore_heartbeat, it wasn't used, and use
watchdog_user to tell if we have a working IPMI device below
us.

ce7fa1c38d ipmi: Add a way to tune some timeouts
By default the retry timeout is 1 second.  Allow that to be modified,
primarily for slow operations, like firmware writes.

Also, the timeout was driven by a 1 second timer, so 1 second really
meant between 0 and 1 second.  Set the default to 2 seconds so it
means between 1 and 2 seconds.

Also allow the time the interface automatically stays in mainenance
mode to be modified from it's default 30 seconds.

Also consolidate some of the timeout and retry setup.

Pull SCSI fixes from James Bottomley:
 "This is a set of minor (and safe changes) that didn't make the initial
  pull request plus some bug fixes.

  The status handling code is actually a running regression from the
  previous merge window which had an incomplete fix (now reverted) and
  most of the remaining bug fixes are for problems older than the
  current merge window"

[ Side note: this merge also takes the base kernel git repository to 6+
  million objects for the first time. Technically we hit it a couple of
  merges ago already if you count all the tag objects, but now it
  reaches 6M+ objects reachable from HEAD.

  I was joking around that that's when I should switch to 5.0, because
  3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
  probably not, even if numerology is about as good a reason as any.

ca4e7c5120 Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
 "The large diff this time around is from the addition of a new clk
  driver for the TI Davinci family of SoCs. So far those clks have been
  supported with a custom implementation of the clk API in the arch port
  instead of in the CCF. With this driver merged we're one step closer
  to having a single clk API implementation.

  The other large diff is from the Amlogic clk driver that underwent
  some major surgery to use regmap. Beyond that, the biggest hitter is
  Samsung which needed some reworks to properly handle clk provider
  power domains and a bunch of PLL rate updates.

  The core framework was fairly quiet this round, just getting some
  cleanups and small fixes for some of the more esoteric features. And
  the usual set of driver non-critical fixes, cleanups, and minor
  additions are here as well.

  Core:
   - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
   - debugfs ops macroized to shave some lines of boilerplate code
   - Always calculate the phase instead of caching it in clk_get_phase()
   - More __must_check on bulk clk APIs

  New Drivers:
   - TI's Davinci family of SoCs
   - Intel's Stratix10 SoC
   - stm32mp157 SoC
   - Allwinner H6 CCU
   - Silicon Labs SI544 clock generator chip
   - Renesas R-Car M3-N and V3H SoCs
   - i.MX6SLL SoCs

  Removed Drivers:
   - ST-Ericsson AB8540/9540

  Updates:
   - Mediatek MT2701 and MT7622 audsys support and MT2712 updates
   - STM32F469 DSI and STM32F769 sdmmc2 support
   - GPIO clks can sleep now
   - Spreadtrum SC9860 RTC clks
   - Nvidia Tegra MBIST workarounds and various minor fixes
   - Rockchip phase handling fixes and a memory leak plugged
   - Renesas drivers switch to readl/writel from clk_readl/clk_writel
   - Renesas gained CPU (Z/Z2) and watchdog support
   - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
   - Qualcomm PM8921 PMIC XO buffers
   - Amlogic migrates to regmap APIs
   - TI Keystone clk latching support
   - Allwinner H3 and H5 video clk fixes
   - Broadcom BCM2835 PLLs needed another bit to enable
   - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix
   - i.MX6UL/ULL epdc_podf support

90fe6f8ff0 firmware: dmi_scan: Fix UUID length safety check
The test which ensures that the DMI type 1 structure is long enough
to hold the UUID is off by one. It would fail if the structure is
exactly 24 bytes long, while that's sufficient to hold the UUID.

I don't expect this bug to cause problem in practice because all
implementations I have seen had length 8, 25 or 27 bytes, in line
with the SMBIOS specifications. But let's fix it still.

b2f3f5920d drm/amd/display: Fix regamma not affecting full-intensity color values
Hardware understands the regamma LUT as a piecewise linear function,
with points spaced exponentially along the range. We previously
programmed the LUT for range [2^-10, 2^0). This causes (normalized)
color values of 1 (=2^0) to miss the programmed LUT, and fall onto the
end region.

For DCE, the end region is extrapolated using a single (base, slope)
pair, using the max y-value from the last point in the curve as base.
This presents a problem, since this value affects all three color
channels. Scaling down the intensity of say - the blue regamma curve -
will not affect it's end region. This is especially noticiable when
using RedShift. It scales down the blue and green channels, but leaves
full-intensity colors unshifted.

Therefore, extend the range to cover [2^-10, 2^1) by programming another
hardware segment, containing only one point. That way, we won't be
hitting the end region.

Note that things are a bit different for DCN, since the end region can
be set per-channel.

bb06ec3145 nvme: expand nvmf_check_if_ready checks
The nvmf_check_if_ready() checks that were added are very simplistic.
As such, the routine allows a lot of cases to fail ios during windows
of reset or re-connection. In cases where there are not multi-path
options present, the error goes back to the callee - the filesystem
or application. Not good.

The common routine was rewritten and calling syntax slightly expanded
so that per-transport is_ready routines don't need to be present.
The transports now call the routine directly. The routine is now a
fabrics routine rather than an inline function.

The routine now looks at controller state to decide the action to
take. Some states mandate io failure. Others define the condition where
a command can be accepted.  When the decision is unclear, a generic
queue-or-reject check is made to look for failfast or multipath ios and
only fails the io if it is so marked. Otherwise, the io will be queued
and wait for the controller state to resolve.

Admin commands issued via ioctl share a live admin queue with commands
from the transport for controller init. The ioctls could be intermixed
with the initialization commands. It's possible for the ioctl cmd to
be issued prior to the controller being enabled. To block this, the
ioctl admin commands need to be distinguished from admin commands used
for controller init. Added a USERCMD nvme_req(req)->rq_flags bit to
reflect this division and set it on ioctls requests.  As the
nvmf_check_if_ready() routine is called prior to nvme_setup_cmd(),
ensure that commands allocated by the ioctl path (actually anything
in core.c) preps the nvme_req(req) before starting the io. This will
preserve the USERCMD flag during execution and/or retry.
