The MCE handler for nfit devices is called for memory errors on a
Non-Volatile DIMM and adds the error location to a 'badblocks' list.
This list is used by the various NVDIMM drivers to avoid consuming known
poison locations during IO.
The MCE handler gets called for both corrected and uncorrectable errors.
Until now, both kinds of errors have been added to the badblocks list.
However, corrected memory errors indicate that the problem has already
been fixed by hardware, and the resulting interrupt is merely a
notification to Linux.
As far as future accesses to that location are concerned, it is
perfectly fine to use, and thus doesn't need to be included in the above
badblocks list.
Add a check in the nfit MCE handler to filter out corrected mce events,
and only process uncorrectable errors.

It's lockless, and userspace might chance it underneath us. That's not
really a problem, all userspace gets is a slightly dysfunctional
lease with the current code. But this might change, and gcc might
decide to reload a few too many times, and then boom. So better safe
than sorry.
v2: Remove the now unused lessor_priv argument from validate_lease()
(Keith).
v3: Actually add everything ... silly me.

When CONFIG_LEDS_CLASS is disabled, or it is a loadable module while
mt76 is built-in, we run into a link error:
drivers/net/wireless/mediatek/mt76/mac80211.o: In function `mt76_register_device':
mac80211.c:(.text+0xb78): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `devm_of_led_classdev_register'
We don't really need a hard dependency here as the driver can presumably
work just fine without LEDs, so this follows the iwlwifi example and
adds a separate Kconfig option for the LED support, this will be available
whenever it will link, and otherwise the respective code gets left out from
the driver object.

Previous commit /adding/ support for 160 MHz chanspecs was incomplete.
It didn't set bandwidth info and didn't extract control channel info. As
the result it was also using uninitialized "sb" var.
This change has been tested for two chanspecs found to be reported by
some devices/firmwares:
1) 60/160 (0xee32)
Before: chnum:50 control_ch_num:36
After: chnum:50 control_ch_num:60
2) 120/160 (0xed72)
Before: chnum:114 control_ch_num:100
After: chnum:114 control_ch_num:120

It seems since we don't have a wakeirq value in the dts, the wakeirq
value in wl1271_probe() is zero, which then causes trouble in
irqd_get_trigger_type(irq_get_irq_data(wakeirq)).
This patch tries to address this by checking if wakeirq is zero,
and not trying to add it to the resources if that is the case.

We tried to revert commit d9c52fd17cb4 ("ath9k: fix tx99 with monitor
mode interface") but accidentally missed part of the locking change.
The lock has to be held earlier so that we're holding it when we do
"sc->tx99_vif = vif;" and also there in the current code there is a
stray unlock before we have taken the lock.

We're no longer programming any watermarks when we're disabling
a pipe. That means ilk_wm_merge() & co. will keep considering
the any pipe that is getting disabled as still enabled. Thus we
either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal
ones (hsw-bdw).
This seems to have been broken by commit b6b178a77210 ("drm/i915:
Calculate ironlake intermediate watermarks correctly, v2."). Before
that we apparently had some difference between the intermediate
and optimal watermarks and so we would program the optiomal ones.
Now intermediate and optimal are identical for disabled pipes
and so we don't program either.
Fix this by programming the intermediate watermarks even for
disabled pipes. We were already doing that for skl+. We'll
leave out gmch platforms for now since those do the merging
in a different manner and should work as is. We'll want to
unify this eventually, but play it safe for now and just put
in a FIXME.

We deinit the lpe audio device before we call
drm_atomic_helper_shutdown(), which means the platform device
may already be gone when it comes time to shut down the crtc.
As we don't know when the last reference to the platform
device gets dropped by the audio driver we can't assume that
the device and its data are still around when turning off the
crtc. Mark the platform device as gone as soon as we do the
audio deinit.

Since we use a 64b virtual GTT irrespective of the system, we want to
ensure that the GTT computations remains 64b even on 32b systems,
including treatment of huge virtual pages.
No code generation changes on 64b:

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.
This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

We deinit the lpe audio device before we call
drm_atomic_helper_shutdown(), which means the platform device
may already be gone when it comes time to shut down the crtc.
As we don't know when the last reference to the platform
device gets dropped by the audio driver we can't assume that
the device and its data are still around when turning off the
crtc. Mark the platform device as gone as soon as we do the
audio deinit.

Patch ad608fbcf166 changed how events were subscribed to address an issue
elsewhere. As a side effect of that change, the "add" callback was called
before the event subscription was added to the list of subscribed events,
causing the first event queued by the add callback (and possibly other
events arriving soon afterwards) to be lost.
Fix this by adding the subscription to the list before calling the "add"
callback, and clean up afterwards if that fails.

Plane input CSC needs to be enabled to convert frambuffers from
YUV to RGB. This is needed for bottom 3 planes on ICL, rest of
the planes have hardcoded conversion and taken care by the legacy
code.
This patch defines the co-efficient values for YUV to RGB conversion
in BT709 and BT601 formats. It programs the coefficients and enables
the plane input csc unit in hardware.
This has been verified and tested by Maarten and the change is working
as expecpted.
v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.
v3: Added individual coefficient matrix (9 values) instead of 6
register values as per Maarten's comment. Also addresed a shift
issue with B channel coefficient.
v4: Added support for Limited Range Color Handling
v5: Fixed Matt and Maarten's review comments.
v6: Added human readable matrix values for YUV to RGB Conversion along
with just the bspec register values, as per Matt's suggestion.
v7: Refactored the code, move csc coefficient programming function to
intel_sprite.c and made it static as per Ville's review comment.
v8: Addressed Ville's review comment. Called the coefficient programming
from within the skl_program_plane and used I915_WRITE_FW instead of
I915_WRITE.
v9: Fixed Ville's review comments.

Defined the plane input csc coefficient registers and macros.
6 registers are used to program a total of 9 coefficients,
added macros to define each of them for all the planes
supporting the feature on pipes. On ICL, bottom 3 planes
have this capability.
v2: Segregated the register macro definition as separate patch
as per Maarten's suggestion.
v3: Removed a redundant 3rd Pipe register definition and
simplified the equally spaced register definition by adding an
offset as per Matt's comment.
v4: No Change

However, the code doesn't check if there were errors other than OK or NACK,

We get a headers_check warning about the newly defined ioctl command
structures:
./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h>
This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

Current check for the last extra TRB for zero and unaligned transfers
does not account for isoc OUT. The last TRB of the Buffer Descriptor for
isoc OUT transfers will be retired with HWO=0. As a result, we won't
return early. The req->remaining will be updated to include the BUFSIZ
count of the extra TRB, and the actual number of transferred bytes
calculation will be wrong.
To fix this, check whether it's a short or zero packet and the last TRB
chain bit to return early.
