important to the different hardware types involved:
- thunderbolt driver updates
- parport updates (people still care...)
- nvmem driver updates
- mei updates (as always)
- hwtracing driver updates
- hyperv driver updates
- extcon driver updates
- ... and a handful of even smaller driver subsystem and individual
driver updates
All of these have been in linux-next with no reported issues"

When cancelling the requests and clearing out the ports following a
successful preemption completion, also clear the active flag. I had
assumed that all preemptions would be followed by an immediate dequeue
(preserving the active user flag), but under rare circumstances we may
be triggering a preemption for the second port only for it to have
completed before the preemotion kicks in; leaving execlists->active set
even though the system is now idle.
We can clear the flag inside the common execlists_cancel_port_requests()
as the other users also expect the semantics of active being cleared.

amdgpu driver checks vgacon_text_force() after some initializations

Two years ago I tried an AMD Radeon E8860 embedded GPU with the drm driver.
The dmesg output included driver warnings about an invalid PCIe lane width.
Tracking the problem back led to si_set_pcie_lane_width_in_smc().
The calculation of the lane widths via ATOM_PPLIB_PCIE_LINK_WIDTH_MASK and
ATOM_PPLIB_PCIE_LINK_WIDTH_SHIFT macros did not increment the resulting
value, per the comment in pptable.h ("lanes - 1"), and per usage elsewhere.
Applying the increment silenced the warnings.
The code has not changed since, so either my analysis was incorrect or the
bug has gone unnoticed. Hence submitting this as an RFC.

initialization
Much error exist in host dmesg during guest boot up with loca display
enabled.
gvt: vgpu 1: invalid range gmadr 0x0 size 0x0
This error happens when qemu get dmabuf info in case that the virtual
display plane is enabled but its base address is an invalid 0, such
case may be true before guest enable its plane. At this moment, its
state is copied from host where the plane may be enabled.
This patch disable primary/sprite/cursor plane at virtual display
initialization, so intel_vgpu_decode_primary/cursor/sprite could
return early as plane is disabled, then plane base check is skipped and
error message disapper.

GVT-g dispatches request to host i915 and depends on i915 notify
ring interrupt mechanism to check completion of request.
For now MI_USER_INTERRUPT in guest requests is passed through
in GVT-g cmd parser and i915 does not use it, which causes
unnecessary interrupt handling in i915.
On the other hand, if several requests from guest are combined into
one request in and contain MI_USER_INTERRUPT in the middle of
combined request. GVT-g still has to wait on the whole request to
complete to inject user interrupts to guest.
This patch makes all the MI_USER_INTERRUPT nop to save some interrupt
handling.
Here is test result to run glmark2 on guest for 10 seconds:
host master interrupts number is reduced from 16021 to 11162
host user interrupts number is reduced from 7936 to 3536

After
commit dd9f31c7a3887950cbd0d49eb9d43f7a1518a356
Author: Imre Deak <imre.deak@intel.com>
Date: Wed Aug 16 17:46:07 2017 +0300
drm/i915/gen9+: Set same power state before hibernation image
save/restore
during hibernation/suspend the power domain functionality got disabled,
after which resume could leave it incorrectly disabled if the ACPI
target state was S0 during suspend and i915 was not loaded by the loader
kernel.
This was caused by not considering if we resumed from hibernation as the
condition for power domains reiniting.
Fix this by simply tracking if we suspended power domains during system
suspend and reinit power domains accordingly during resume. This will
result in reiniting power domains always when resuming from hibernation,
regardless of the platform and whether or not i915 is loaded by the
loader kernel.
The reason we didn't catch this earlier is that the enabled/disabled
state of power domains during PMSG_FREEZE/PMSG_QUIESCE is platform
and kernel config dependent: on my SKL the target state is S4
during PMSG_FREEZE and (with the driver loaded in the loader kernel)
S0 during PMSG_QUIESCE. On the reporter's machine it's S0 during
PMSG_FREEZE but (contrary to this) power domains are not initialized
during PMSG_QUIESCE since i915 is not loaded in the loader kernel, or
it's loaded but without the DMC firmware being available.

We were relying on the uncached reads when processing the CSB to provide
ourselves with the serialisation with the interrupt handler (so we could
detect new interrupts in the middle of processing the old one). However,
in commit 767a983ab255 ("drm/i915/execlists: Read the context-status HEAD
from the HWSP") those uncached reads were eliminated (on one path at
least) and along with them our serialisation. The result is that we
would very rarely miss notification of a new interrupt and leave a
context-switch unprocessed, hanging the GPU.

If the GPU is stuck waiting for an event or for a semaphore, we need to
reset the GPU in order to recover. We have to tell the reset routine
which engines we want reset, but we were still using the old interface
and declaring it as "not-fatal".

If bios sets up an MST output and hardware state readout code sees this is
an SST configuration, when disabling the encoder we end up calling
->post_disable_dp() hook instead of the MST version. Consequently, we write
to the DP_SET_POWER dpcd to set it D3 state. Further along when we try
enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up
the MST hub. This results in continuous link training failures which keep
the system busy delaying boot. We could identify bios MST boot discrepancy
and handle it accordingly but a simple way to solve this is to write to the
DP_SET_POWER dpcd for MST too.

v2: use temporaries to trivially reduces object size.
The for-loops process data in the mclk_table but use slck_table.count
as the loop index limit. I believe these are cut-n-paste errors from
the previous almost identical loops as indicated by static analysis.
Fix these.

Apparently xf86-video-vmware leaves the mode->type uninitialized
when feeding the mode to the kernel. Thus we have no choice but
to accept the garbage in. We'll just ignore any of the bits we
don't want. The mode type is just a hint anyway, and more
useful for the kernel->userspace direction.
