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)
v4: Fixed vfunc prototype (Lionel)

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:

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
trigger" patch Ville Syrjälä sent a while back

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()

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- Properly report when a function wildcard produces no matches in 'perf probe'

- Balance opening and reading events in 'perf stat', which could cause
it to get stuck trying to close invalid file descriptors (Mark Rutland)
Infrastructure changes:
- Copy more headers from the kernel, this time for headers that
were just including the contents of its kernel counterparts, should
help resolving the problems with linux-next, where some uapi related
patches seem to be breaking tools/object/ build. (Arnaldo Carvalho de Melo)
Some more combing will be done, but at least it is possible to build
perf out of tree, via a detached tarball (make help | grep perf),
without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo)

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.

Warn unmatched function filter correctly instead of warning
"symbol-loading error", since that can be a filter issue.
From the technical point of view, this adds a filter chech in map__load
and if there is a filter, it returns -2 (filter-out), instead of -1
(error), and perf-probe checks it and change message.
E.g. without this fix:

no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
With this fix:

In some cases it's necessry to figure out the map-local index of a given
Linux logical CPU ID. Add a new helper, cpu_map__idx, to acquire this.
As the logic is largely the same as the existing cpu_map__has, this is
rewritten in terms of the new helper.
At the same time, add the inverse operation, cpu_map__cpu, which yields
the logical CPU id for a map-local index. While this can be performed
manually, wrapping this in a helper can make code more legible.

In create_perf_stat_counter, when a target CPU has not been provided, we
call __perf_evsel__open with empty_cpu_map, and open a single FD per
thread. However, in read_counter we assume that we opened events for the
product of threads and CPUs described in the evsel's cpu_map.
Thus, if an evsel has a cpu_map with more than one entry, we will
attempt to access FDs that we didn't open. This could result in a number
of problems (e.g. blocking while reading from STDIN if the fd memory
happened to be initialised to zero).
This is problematic for systems were a logical CPU PMU covers some
arbitrary subset of CPUs. The cpu_map of any evsel for that PMU will be
initialised based on the cpumask exposed through sysfs, even if the user
requests per-thread events.

The tree returned from of_fdt_unflatten_tree cannot be attached to the
live tree because it is not marked as detached so mark it as such. The
dt resolver checks the flag and refuses to process the tree otherwise.

Since we set ATA_MAX_SECTORS_LBA48 to 65535 to avoid the corner case
in some drives that commands with "count" set to 0000h (which
reprsents 65536) does not work as expected, lba_48_ok(), which is
used for number-of-blocks checking when libata pack commands, should
use the same limit as well. In fact, there is no reason for the two
functions not to use the macros anyway.

It can be hard for people not familiar with the CoreSight IP blocks
to make sense of the acronyms found in the current bindings. As such
this patch expands each acronym in the hope of providing a better
description of the IP block they represent.

Document cavium-pip rx-delay/tx-delay properties. Currently the board
specific values need to be hardcoded in the platform code, which we
want to avoid when moving to DT-only booting.
