Pull drm fixes from Dave Airlie: "nouveau, amdgpu, i915, vc4, omap, exynos and atomic fixes. As last week seemed a bit slow, we got a few more fixes this week. The main stuff is two weeks of fixes for amdgpu, some missing bits of vega12 atom firmware support were added, and some power management fixes. Nouveau got two regression fixes for an DP MST deadlock and a random oops fix. i915 got an LVDS panel timeout fix 2 WARN fixes. exynos fixed a pagefault issue in the mixer driver. vc4 has an oops fix. omap had a bunch of uninit var and error-checking fixes. Two atomic modesetting state fixes.

Commit 3a4d44b6 ("ntp: Move adjtimex related compat syscalls to native counterparts") removed the memset() in compat_get_timex(). Since then, the compat adjtimex syscall can invoke do_adjtimex() with an uninitialized ->tai. If do_adjtimex() doesn't write to ->tai (e.g. because the arguments are invalid), compat_put_timex() then copies the uninitialized ->tai field to userspace. Fix it by adding the memset() back.

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] Signed-off-by:

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 a2936e3d ("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: [ 0.762117] [drm:intel_dump_pipe_config [i915]] requested mode: [ 0.762142] [drm:drm_mode_debug_printmodeline [drm]] Modeline 0:"1366x768" 60 72143 1366 1414 1446 1526 768 771 777 784 0x40 0xa ...

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.
