When the user presses 'f' to disable events the visual cues are, well,
the percentages not changing and the number of events freezing.
Be more explicit by changing the help line at the bottom of the screen
to show the following messages when 'f' is pressed:
"Press 'f' again to re-enable the events"
And then, when 'f' is pressed again:
"Press 'f' to disable the events or 'h'

The hists_browser was replacing whatever helpline provided by 'top' or
'report' with a static "Press '?' for help on key bindings", fix it.
Now the message passed by top appears at the bottom of the screen:
"For a higher level overview, try: perf top --sort comm,dso"
As well the message that will be added when the user presses 'f' to
disable the events, something along the lines of "press f again to
re-enable...".

The 'f' hotkey is only used when in 'top', dynamic mode, to
enable/disable events, currently not making sense in the 'report',
static mode, where we can't go from showing the histogram entries
created from a perf.data file to adding more events after recreating the
evlist created from the perf.data file, albeit possible, this is not
implemented right now.

wake_futex_pi() wakes the task before releasing the hash bucket lock
(HB). The first thing the woken up task usually does is to acquire the
lock which requires the HB lock. On SMP Systems this leads to blocking
on the HB lock which is released by the owner shortly after.
This patch rearranges the unlock path by first releasing the HB lock and
then waking up the task.

This fixes io submit ioctl handling when using extended metadata
formats. When these formats are used, the user provides a single virtually
contiguous buffer containing both the block and metadata interleaved,
so the metadata size needs to be added to the total length and not mapped
as a separate transfer.
The command is also driver generated, so this patch does not enforce
blk-integrity extensions provide the metadata buffer.

The thread-stack represents a thread's current stack. When a thread
exits there can still be many functions on the stack e.g. exit() can be
called many levels deep, so all the callers will never return. To get
that information output, the thread-stack must be flushed.
Previously it was assumed the thread-stack would be flushed when the
struct thread was deleted. With thread ref-counting it is no longer
clear when that will be, if ever. So instead explicitly flush all the
thread-stacks at the end of a session.

This patch resolves the issue that refresh rate got low
at extension mode test with fimd and vidi combination.
The problem was because atomic_commit callback waited
for the completion of vblank to gaurantee crtc relevant
registers are updated from shadow registers to real ones.
However, the waiting there is really unnecessary because
page flip operation does already it.

This patch resolves page fault issue with iommu and atomic feature
when modetest test application is terminated.
ENWIN_F field of WINCONx register enables or disable a dma channel to
each hardware overlay - the value of the field will be updated to real
register after vsync.
So this patch makes sure the dma channel is disabled by waiting for vsync
one time after clearing shadow registers to all dma channels.

When the fimd is disabled by fimd_disable(), enabled overlay layers also
are disabled. If clocks for fimd are enabled by fimd_enable() on this
case, it can lead IOMMU page fault. The reason is that VIDCON0_ENVID and
VIDCON0_ENVID_F bits of VIDCON0 register are set still even though fimd
is disabled, so it may continue display output of prior when clocks for
fimd are enabled again.

With atomic modesetting all the control for CRTC, Planes, Encoders and
Connectors should come from DRM core, so the driver is not allowed to
enable or disable planes from inside the crtc_enable()/disable() call.
But it needs to disable planes with crtc_disable in exynos driver
internally. Because crtc is disabled before plane is disabled, it means
plane_disable just returns without any register changes, then we cannot
be sure setting register to disable plane when crtc is disable.
This patch removes this chainned calls to enable plane from exynos hw
drivers code letting only DRM core touch planes except to disable plane.
Also it leads eliminable enabled and resume of struct exynos_drm_plane.

exynos_dsi_host_transfer() can be called through a panel driver while
DSI is turning down. It is possible because the function checks only
whether DSI is initialized or not, and there is a moment which DSI is
set by uninitialized, but DSI is still turning down. To prevent it,
DSI must be set by disabled before starting to be turned down, and
exynos_dsi_host_transfer() must check whether DSI is enabled or not.

SoC checking code is not necessary anymore, as exynos_drm_match_add and
exynos_drm_platform_probe already properly handles situation when there are
no Exynos DRM components.

In case there are multiple pipelines and deferred probe occurs, only components
of the first pipeline were bound. As a result only one pipeline was available.
The main cause of this issue was dynamic generation of component match table -
every component driver during probe registered itself on helper list, if there
was at least one pipeline present on this list component match table were
created without deferred components.
This patch removes this helper list, instead it creates match table from
existing devices requiring exynos_drm KMS drivers. This way match table do not
depend on probe/deferral order and contains all KMS components.
As a side effect patch makes the code cleaner and significantly smaller.

Code registering different drivers and simple platform devices was dispersed
across multiple sub-modules. This patch moves it to one place. As a result
initialization code is shorter and cleaner and should simplify further
development.

This patch makes one of Linux framebuffer and DRM CRTC drivers
to be enabled.
Display controllers, FIMD and DECON, can be controlled by Linux
framebuffer or DRM CRTC drivers so only one of them should be
enabled.
