GFP_TRANSHUGE tries very hard to allocate huge pages, which can result
in long delays with high memory pressure. I have observed firefox
freezing for up to around a minute due to this while restic was taking
a full system backup.
Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT |
__GFP_NORETRY instead, in order to fail quickly when there are no huge
pages available.
Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed
up in the background if necessary.
With these changes, I'm no longer seeing freezes during a restic backup.

Fix `[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to
power on` in kernel log at boot time.
Toshiba Satellite Z930 laptops needs between 1 and 2 seconds to power
on its screen during Intel i915 DRM initialization. This currently
results in a `[drm:intel_enable_lvds] *ERROR* timed out waiting for
panel to power on` message appearing in the kernel log during boot
time and when stopping the machine.
This change increases the timeout of the `intel_enable_lvds` function
from 1 to 5 seconds, letting enough time for the Satellite 930 LCD
screen to power on, and suppressing the error message from the kernel
log.
This patch has been successfully tested on Linux 4.14 running on a
Toshiba Satellite Z930.
[vsyrjala: bump the timeout from 2 to 5 seconds to match the DP
code and properly cover the max hw timeout of ~4 seconds, and
drop the comment about the specific machine since this is not
a particulary surprising issue, nor specific to that one machine]

During state readout we first read out the pipe src size, store
that information in the user mode h/vdisplay, but later on we overwrite
that with the actual crtc timings. That makes our read out crtc state
inconsistent with itself when the BIOS has enabled the panel fitter to
scale the pipe contents. Let's preserve the pipe src size based
information in the user mode to make things consistent again.
This fixes a problem introduced by commit a2936e3d9a ("drm/i915:
Use drm_mode_get_hv_timing() to populate plane clip rectangle")
where the inconsistent state is now leading the plane clipping code
to report a failure on account the plane dst coordinates not matching
the user mode size. Previously we did the plane clipping based on
the pipe src size instead and thus never noticed the inconsistency.
The failure manifests as a WARN:

On intel_dp_compute_config() we were calculating the needed vco
for eDP on gen9 and we stashing it in
intel_atomic_state.cdclk.logical.vco
However few moments later on intel_modeset_checks() we fully
replace entire intel_atomic_state.cdclk.logical with
dev_priv->cdclk.logical fully overwriting the logical desired
vco for eDP on gen9.
So, with wrong VCO value we end up with wrong desired cdclk, but
also it will raise a lot of WARNs: On gen9, when we read
CDCLK_CTL to verify if we configured properly the desired
frequency the CD Frequency Select bits [27:26] == 10b can mean
337.5 or 308.57 MHz depending on the VCO. So if we have wrong
VCO value stashed we will believe the frequency selection didn't
stick and start to raise WARNs of cdclk mismatch.

Clear the old_state and new_state pointers for every object in
drm_atomic_state_default_clear(). Otherwise
drm_atomic_get_{new,old}_*_state() will hand out stale pointers to
anyone who hasn't first confirmed that the object is in fact part of
the current atomic transcation, if they are called after we've done
the ww backoff dance while hanging on to the same drm_atomic_state.
For example, handle_conflicting_encoders() looks like it could hit
this since it iterates the full connector list and just calls
drm_atomic_get_new_connector_state() for each.
And I believe we have now witnessed this happening at least once in
i915 check_digital_port_conflicts(). Commit 8b69449d26 ("drm/i915:
Remove last references to drm_atomic_get_existing* macros") changed
the safe drm_atomic_get_existing_connector_state() to the unsafe
drm_atomic_get_new_connector_state(), which opened the doors for
this particular bug there as well.

drm/vc4: Make sure vc4_bo_{inc,dec}_usecnt() calls are balanced
Commit b9f19259b8 ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl")
introduced a mechanism to mark some BOs as purgeable to allow the driver
to drop them under memory pressure. In order to implement this feature
we had to add a mechanism to mark BOs as currently used by a piece of
hardware which materialized through the ->usecnt counter.
Plane code is supposed to increment usecnt when it attaches a BO to a
plane and decrement it when it's done with this BO, which was done in
the ->prepare_fb() and ->cleanup_fb() hooks. The problem is, async page
flip logic does not go through the regular atomic update path, and
->prepare_fb() and ->cleanup_fb() are not called in this case.
Fix that by manually calling vc4_bo_{inc,dec}_usecnt() in the
async-page-flip path.
Note that all this should go away as soon as we get generic async page
flip support in the core, in the meantime, this fix should do the
trick.

At least since the atomic port, the vmwgfx fbdev code is taking
a number of unnecessary modeset locks. In particular the
kms_set_config() function will grab its own locks, leading to
locking retries. So avoid drm_modeset_lock_all() and instead
provide a local acquire context for kms_set_config(). Also have the
vmw_kms_fbdev_init data itself grab the lock that it needs.
This also fixed a long standing problem that vmw_fb_close() didn't
provide an acquire context for kms_set_config(), causing potential
warnings and hangs during driver unload. This problem was uncovered by the

The reverted commit broke LVDS output on TBS A711 Tablet. That tablet
has simple-panel node that has fixed pixel clock-frequency that A83T
SoC used in the tablet can't generate exactly.
Requested rate is 52000000 and rounded_rate is calculated as 51857142.
It's close enough for it to work in practice, but with strict check
in the reverted commit, the mode is rejected needlessly in this case.
DT allows to specify a range of values for simple-panel/clock-frequency,
but driver doesn't respect that ATM. Given that TBS A711 is the single
user of sun4i-lvds driver, let's revert that commit for now, until
a better solution for the problem is found.
