commit 0d8359620d9b ("zram: support page writeback") introduced two
problems. It overwrites writeback_store's return value as kstrtol's
return value, which makes return value zero so user could see zero as
return value of write syscall even though it wrote data successfully.
It also breaks index value in the loop in that it doesn't increase the
index any longer. It means it can write only first starting block index
so user couldn't write all idle pages in the zram so lose memory saving
chance.
This patch fixes those issues.

writeback_store's return value is overwritten by submit_bio_wait's return
value. Thus, writeback_store will return zero since there was no IO
error. In the end, write syscall from userspace will see the zero as
return value, which could make the process stall to keep trying the write
until it will succeed.

Say we have two planes enabled with watermarks configured
as follows:
plane A: wm0=enabled/can_sagv=false, wm1=enabled/can_sagv=true
plane B: wm0=enabled/can_sagv=true, wm1=disabled
This is possible since the latency we use to calculate
can_sagv may not be the same for both planes due to
skl_needs_memory_bw_wa().
In this case skl_crtc_can_enable_sagv() will see that
both planes have enabled at least one watermark level
with can_sagv==true, and thus proceeds to allow SAGV.
However, since plane B does not have wm1 enabled
plane A can't actually use it either. Thus we are
now running with SAGV enabled, but plane A can't
actually tolerate the extra latency it imposes.
To remedy this only allow SAGV on if the highest common
enabled watermark level for all active planes can tolerate
the extra SAGV latency.

On HSW/BDW with VT-d active the first tile row scanned out
after the first async flip of the frame often ends up corrupted.
Whether the corruption happens or not depends on the scanline
on which the async flip happens, but the behaviour seems very
consistent. Ie. the same set of scanlines (which are most scanlines)
always show the corruption. And another set of scanlines (far less
of them) never shows the corruption.
I discovered that disabling the fetch-stride stretching
feature cures the corruption. This is some kind of TLB related
prefetch thing AFAIK. We already disable it on SNB primary
planes due to a documented workaround. The hardware folks
indicated that disabling this should be fine, so let's go
with that.
And while we're here, let's document the relevant bits on all
pre-skl platforms.

We are required to call dev_pm_opp_put() from outside of the
opp_table->lock as debugfs removal needs to happen lock-less to avoid
circular dependency issues.
commit cf1fac943c63 ("opp: Reduce the size of critical section in
_opp_kref_release()") tried to fix that introducing a new routine
_opp_get_next() which keeps returning OPPs that can be freed by the
callers and this routine shall be called without holding the
opp_table->lock.
Though the commit overlooked the fact that the OPPs can be referenced by
other users as well and this routine will end up dropping references
which were taken by other users and hence freeing the OPPs prematurely.
In effect, other users of the OPPs will end up having invalid pointers
at hand. We didn't see any crash reports earlier as the exact situation
never happened, though it is certainly possible.
We need a way to mark which OPPs are no longer referenced by the OPP
core, so we don't drop extra references to them accidentally.
This commit adds another OPP flag, "removed", which is used to track
this. And now we should never end up dropping extra references to the
OPPs.

Commit 311a50e76a33 ("drm/i915: Add support for mandatory cmdparsing")
introduced mandatory command parsing but setup failures were not
translated into wedging the GPU which was probably the intent.
Possible errors come in two categories. Either the sanity check on
internal tables has failed, which should be caught in CI unless an
affected platform would be missed in testing; or memory allocation failure
happened during driver load, which should be extremely unlikely but for
correctness should still be handled.
v2:
* Tidy coding style. (Chris)

Let's check that we actually found the PLL before doing the

even survive such misprogramming without hanging but no

Panel power sequence says timing T8 (time from link idle to turn on
the backlight) should be at least 50 ms. This is what the .enable
delay in simple-panel is for, so set it. NOTE: this overlaps with the
80 ms .prepare_to_enable delay on purpose. The data sheet says that
at least 80 ms needs to pass between HPD going high and turning on the
backlight and that at least 50 ms needs to pass between the link idle
and the backlight going on. Thus it works like this on the system in
front of me:
* In bridge chip pre_enable call drm_panel_prepare()
* drm_panel_prepare() -> panel_simple_prepare()
* Wait for HPD GPIO to go high.
* Start counting for 80 ms (store in prepared_time)
* In bridge chip enable, train link then call drm_panel_enable()
* drm_panel_enable() -> panel_simple_enable()
* panel_simple_enable() does hardcoded 50 ms delay then enforces 80 ms
from HPD going high (in case the bridge took less than 30 ms to
enable / link train).
* drm_panel_enable() -> backlight_enable().

This panel is quite similar to the similarly named N116BGE panel (the
nominal timings are, in fact identical). However, let's add a new
entry because the full range of clocks listed for N116BGE aren't
supported for N116BCA-EA1, at least according to the datasheet.

On an Innolux N116BCA panel that I have in front of me, sometimes HPD
simply doesn't assert no matter how long you wait for it. As per the
very wise advice of The IT Crowd ("Have you tried turning it off and
on again?") it appears that power cycling is enough to kick this panel
back into a sane state.
>From tests on this panel, it appears that leaving it powered off for a
while stimulates the problem. Adding a 6 second sleep at the start of
panel_simple_prepare_once() makes it happen fairly reliably and, with
this delay, I saw up to 3 retries needed sometimes. Without the 6
second sleep, however, the panel came up much more reliably the first
time or after only 1 retry.
While it's unknown what the problems are with this panel (and probably
the hardware should be debugged), adding a few retries to the power on
routine doesn't seem insane. Even if this panel's problems are
attributed to the fact that it's pre-production and/or can be fixed,
retries clearly can help in some cases and really don't hurt.

If a panel has an hpd_absent_delay specified then we know exactly how
long the maximum time is before HPD must be asserted. That means we
can use it as a timeout for polling the HPD pin instead of using an
arbitrary timeout. This is especially useful for dealing with panels
that periodically fail to power on and need to be retried. We can
detect the problem sooner.

If the HPD signal never asserts in panel_simple_prepare() and we
return an error, we should unset the enable GPIO and disable the
regulator to make it consistent for the caller.
At the moment I have some hardware where HPD sometimes doesn't assert.
Obviously that needs to be debugged, but this patch makes it so that
if I add a retry that I can make things work.

If port terminations are detected in suspend, but link never reaches U0
then xHCI may have an internal uncleared wake state that will cause an
immediate wake after suspend.
This wake state is normally cleared when driver clears the PORT_CSC bit,
which is set after a device is enabled and in U0.
Write 1 to clear PORT_CSC for ports that don't have anything connected
when suspending. This makes sure any pending internal wake states in
xHCI are cleared.

I've confirmed that both the ASMedia ASM1042A and ASM3242 have the same
problem as the ASM1142 and ASM2142/ASM3142, where they lose some of the
upper bits of 64-bit DMA addresses. As with the other chips, this can
cause problems on systems where the upper bits matter, and adding the
XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.

A xHC USB 3 port might miss the first wake signal from a USB 3 device
if the port LFPS reveiver isn't enabled fast enough after xHC resume.
xHC host will anyway be resumed by a PME# signal, but will go back to
suspend if no port activity is seen.
The device resends the U3 LFPS wake signal after a 100ms delay, but
by then host is already suspended, starting all over from the
beginning of this issue.
USB 3 specs say U3 wake LFPS signal is sent for max 10ms, then device
needs to delay 100ms before resending the wake.
Don't suspend immediately if port activity isn't detected in resume.
Instead add a retry. If there is no port activity then delay for 120ms,
and re-check for port activity.

On some systems rt2800usb and mt7601u devices are unable to operate since
commit f8f80be501aa ("xhci: Use soft retry to recover faster from
transaction errors")
Seems that some xHCI controllers can not perform Soft Retry correctly,
affecting those devices.
To avoid the problem add xhci->quirks flag that restore pre soft retry
xhci behaviour for affected xHCI controllers. Currently those are
AMD_PROMONTORYA_4 and AMD_PROMONTORYA_2, since it was confirmed
by the users: on those xHCI hosts issue happen and is gone after
disabling Soft Retry.

Recent patch to prevent calling __nvme_fc_abort_outstanding_ios in
interrupt context results in a possible race condition. A controller
reset results in errored io completions, which schedules error
work. The change of error work to a work element allows it to fire
after the ctrl state transition to NVME_CTRL_CONNECTING, causing
any outstanding io (used to initialize the controller) to fail and
cause problems for connect_work.
Add a state check to only schedule error work if not in the RESETTING
state.
