e4add7b6be Input: synaptics-rmi4 - fix maximum size check for F12 control register 8
According to the RMI4 spec the maximum size of F12 control register 8 is
15 bytes. The current code incorrectly reports an error if control 8 is
greater then 14. Making sensors with a control register 8 with 15 bytes
unusable.

eabfdda934 net: switchdev: change ageing_time type to clock_t
The switchdev value for the SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME
attribute is a clock_t and requires to use helpers such as
clock_t_to_jiffies() to convert to milliseconds.

Change ageing_time type from u32 to clock_t to make it explicit.

Since Thadeu left IBM, EHEA has gone mostly unmaintained, since his email
address doesn't work anymore.  I'm stepping up to help maintain this
driver upstream.

I'm adding Thadeu's personal e-mail address in Cc, hoping that we can

5ec6df777b Merge branch 'mlx4-fixes'
Tariq Toukan says:

====================
Safe flow for mlx4_en configuration change

This patchset improves the mlx4_en driver resiliency, especially on
systems with low memory.  Upon a configuration change that requires
the allocation of new resources, we first try to allocate, prior to
destroying the current ones.  Once it is successfully done,
we release the old resources and attach the new ones.  Otherwise, we
stay with a functioning interface having the same old configuration.

This improvement became of greater significance after removing the use
of vmap.

ec25bc04ed net/mlx4_en: Add resilience in low memory systems
This patch fixes the lost of Ethernet port on low memory system,
when driver frees its resources and fails to allocate new resources.
Issue could happen while changing number of channels, rings size or
changing the timestamp configuration.
This fix is necessary because of removing vmap use in the code.
When vmap was in use driver could allocate non-contiguous memory
and make it contiguous with vmap. Now it could fail to allocate
a large chunk of contiguous memory and lose the port.
Current code tries to allocate new resources and then upon success
frees the old resources.

a72255983f nfit: make DIMM DSMs optional
Commit 4995734e97 "acpi, nfit: fix acpi_check_dsm() vs zero functions
implemented" attempted to fix a QEMU regression by supporting its usage
of a zero-mask as a valid response to a DSM-family probe request.
However, this behavior breaks HP platforms that return a zero-mask by
default causing the probe to misidentify the DSM-family.

Instead, the QEMU regression can be fixed by simply not requiring the DSM
family to be identified.

This effectively reverts commit 4995734e97, and removes the DSM
requirement from the init path.

the drm_irq.h include in drmP.h needs to be in just the right spot :(

fa95986095 drm/i915: Set legacy properties when using legacy gamma set IOCTL. (v2)
The i915 driver is now using atomic properties and atomic commit
to handle the legacy set gamma IOCTL. However, if the driver is
configured without atomic (nuclear_pageflip = false), it won't
update the legacy properties for degamma_lut, gamma_lut and ctm
leaving them out of sync with the atomic version of the properties.

Until the driver is full atomic, make sure we update the non-atomic
version of the properties.

v2: Update the comment with a FIXME.  (Daniel)

v3: Update arguments of the gamma_set vfunc (Lionel)

84c8e0963d drm/i915: Enable polling when we don't have hpd
Unfortunately, there's two situations where we lose hpd right now:
- Runtime suspend
- When we've shut off all of the power wells on Valleyview/Cherryview

While it would be nice if this didn't cause issues, this has the
ability to get us in some awkward states where a user won't be able to
get their display to turn on. For instance; if we boot a Valleyview
system without any monitors connected, it won't need any of it's power
wells and thus shut them off. Since this causes us to lose HPD, this
means that unless the user knows how to ssh into their machine and do a
manual reprobe for monitors, none of the monitors they connect after
booting will actually work.

Eventually we should come up with a better fix then having to enable
polling for this, since this makes rpm a lot less useful, but for now
the infrastructure in i915 just isn't there yet to get hpd in these
situations.

Changes since v1:
 - Add comment explaining the addition of the if
   (!mode_config->poll_running) in intel_hpd_init()
 - Remove unneeded if (!dev->mode_config.poll_enabled) in
   i915_hpd_poll_init_work()
 - Call to drm_helper_hpd_irq_event() after we disable polling
 - Add cancel_work_sync() call to intel_hpd_cancel_work()

Changes since v2:
 - Apparently dev->mode_config.poll_running doesn't actually reflect
   whether or not a poll is currently in progress, and is actually used
   for dynamic module paramter enabling/disabling. So now we instead
   keep track of our own poll_running variable in dev_priv->hotplug
 - Clean i915_hpd_poll_init_work() a little bit

Changes since v3:
 - Remove the now-redundant connector loop in intel_hpd_init(), just
   rely on intel_hpd_poll_enable() for setting connector->polled
   correctly on each connector
 - Get rid of poll_running
 - Don't assign enabled in i915_hpd_poll_init_work before we actually
   lock dev->mode_config.mutex
 - Wrap enabled assignment in i915_hpd_poll_init_work() in READ_ONCE()
   for doc purposes
 - Do the same for dev_priv->hotplug.poll_enabled with WRITE_ONCE in
   intel_hpd_poll_enable()
 - Add some comments about racing not mattering in intel_hpd_poll_enable

Changes since v4:
 - Rename intel_hpd_poll_enable() to intel_hpd_poll_init()
 - Drop the bool argument from intel_hpd_poll_init()
 - Remove redundant calls to intel_hpd_poll_init()
 - Rename poll_enable_work to poll_init_work
 - Add some kerneldoc for intel_hpd_poll_init()
 - Cross-reference intel_hpd_poll_init() in intel_hpd_init()
 - Just copy the loop from intel_hpd_init() in intel_hpd_poll_init()

Changes since v5:
 - Minor kerneldoc nitpicks

21842ea84f drm/i915/vlv: Disable HPD in valleyview_crt_detect_hotplug()
One of the things preventing us from using polling is the fact that
calling valleyview_crt_detect_hotplug() when there's a VGA cable
connected results in sending another hotplug. With polling enabled when
HPD is disabled, this results in a scenario like this:

- We enable power wells and reset the ADPA
- output_poll_exec does force probe on VGA, triggering a hpd
- HPD handler waits for poll to unlock dev->mode_config.mutex
- output_poll_exec shuts off the ADPA, unlocks dev->mode_config.mutex
- HPD handler runs, resets ADPA and brings us back to the start

This results in an endless irq storm getting sent from the ADPA
whenever a VGA connector gets detected in the middle of polling.

Somewhat based off of the "drm/i915: Disable CRT HPD around force

4c732e6ee9 drm/i915/vlv: Reset the ADPA in vlv_display_power_well_init()
While VGA hotplugging worked(ish) before, it looks like that was mainly
because we'd unintentionally enable it in
valleyview_crt_detect_hotplug() when we did a force trigger. This
doesn't work reliably enough because whenever the display powerwell on
vlv gets disabled, the values set in VLV_ADPA get cleared and
consequently VGA hotplugging gets disabled. This causes bugs such as one
we found on an Intel NUC, where doing the following sequence of
hotplugs:

      - Disconnect all monitors
      - Connect VGA
      - Disconnect VGA
      - Connect HDMI

Would result in VGA hotplugging becoming disabled, due to the powerwells
getting toggled in the process of connecting HDMI.

Changes since v3:
 - Expose intel_crt_reset() through intel_drv.h and call that in
   vlv_display_power_well_init() instead of
   encoder->base.funcs->reset(&encoder->base);

Changes since v2:
 - Use intel_encoder structs instead of drm_encoder structs

Changes since v1:
 - Instead of handling the register writes ourself, we just reuse
   intel_crt_detect()
 - Instead of resetting the ADPA during display IRQ installation, we now
   reset them in vlv_display_power_well_init()

0564bf0afa net/sched/sch_htb: clamp xstats tokens to fit into 32-bit int
In kernel HTB keeps tokens in signed 64-bit in nanoseconds. In netlink
protocol these values are converted into pshed ticks (64ns for now) and
truncated to 32-bit. In struct tc_htb_xstats fields "tokens" and "ctokens"
are declared as unsigned 32-bit but they could be negative thus tool 'tc'
prints them as signed. Big values loose higher bits and/or become negative.

This patch clamps tokens in xstat into range from INT_MIN to INT_MAX.
In this way it's easier to understand what's going on here.

ed2eebbd61 drm/i915: add missing condition for committing planes on crtc
The i915 driver checks for color management properties changes as part
of a plane update. Therefore a color management update must imply a
plane update, otherwise we never update the transformation matrixes
and degamma/gamma LUTs.

v2: add comment about moving the commit of color management registers
    to an async worker

v3: Commit color management register right after vblank

v4: Move back color management commit condition together with planes
    commit

v5: Trigger color management commit through the planes commit (Daniel)

v6: Make plane change update more readable
