This mouse sold by Corsair as Scimitar PRO RGB defines two consecutive
Logical Minimum items in its Application (Consumer.0001) report making
it non parseable. This patch fixes the report descriptor overriding
byte 77 in rdesc from 0x16 (Logical Minimum with 16 bits value) to 0x26
(Logical Maximum with 16 bits value).

Commit 5b779fc introduces the manual release of resources in wacom_remove() as
an addition to the driver's use of devm. The EKR resources can only be
released through wacom_remote_destroy_one() so we skip the manual release for
it.

When snd_seq_pool_done() is called, it marks the closing flag to
refuse the further cell insertions. But snd_seq_pool_done() itself
doesn't clear the cells but just waits until all cells are cleared by
the caller side. That is, it's racy, and this leads to the endless
stall as syzkaller spotted.
This patch addresses the racy by splitting the setup of pool->closing
flag out of snd_seq_pool_done(), and calling it properly before
snd_seq_pool_done().

CONFIG_SND_X86 is a menu config to filter only for x86-specific
drivers in its sub-menu, and this doesn't have to be tristate but
rather it should be a bool. Also, like other sub-menu configs, it's
more user-friendly to be default=y; it's merely a menu config and the
actual drivers are configured in the sub-menu, after all.

We get a warning with gcc-7 about a pointless comparison when
using a linear memmap:

drivers/gpu/drm/i915/selftests/scatterlist.c:219:66: error: self-comparison always evaluates to false [-Werror=tautological-compare]
Splitting out the comparison into a separate function avoids the warning

As intel_engine_init_global_seqno() may be called by
nop_submit_request() from inside irq context, we have to use atomic
versions of kmap/kunmap. This is rare as this requires using gen8 legacy

intel_engine_wakeup() is called by nop_request_submit() which is
installed to handle third party fences completed from within irq
context. As such, it needs the full irqsave/irqrestore and not the
partial spin_irq_lock handling.

This patch does following:
- Adds a new structure (drm_hdmi_info) in drm_display_info.
This structure will be used to save and indicate if sink
supports advanced HDMI 2.0 features
- Adds another structure drm_scdc within drm_hdmi_info, to
reflect scdc support and capabilities in connected HDMI 2.0 sink.
- Checks the HF-VSDB block for presence of SCDC, and marks it
in scdc structure
- If SCDC is present, checks if sink is capable of generating
SCDC read request, and marks it in scdc structure.
V2: Addressed review comments
Thierry:
- Fix typos in commit message and make abbreviation consistent
across the commit message.
- Change structure object name from hdmi_info -> hdmi
- Fix typos and abbreviations in description of structure drm_hdmi_info
end the description with a full stop.
- Create a structure drm_scdc, and keep all information related to SCDC
register set (supported, read request supported) etc in it.
Ville:
- Change rr -> read_request
- Call drm_detect_scrambling function drm_parse_hf_vsdb so that all

patches.

This reverts commit 3f91a89d424a79f8082525db5a375e438887bb3e.
Now that we do have the machinery for using the radix MMU under a
hypervisor, the extra check and comment introduced in 3f91a89d424a are
no longer correct. The result is that when booted under a hypervisor
that only allows use of radix, we clear the MMU_FTR_TYPE_RADIX and
then set it again, and print a warning about ignoring the
disable_radix command line option, even though the command line does
not include "disable_radix".

DSI forwards te-gpios interrupts to display controller, but if display
controller works in HW-TRIGGER mode this interrupt is not necessary.
Making te-gpios property optional allows to avoid generating spare
interrupts.
And also if panel device node of command mode panel device doesn't provide
te-gpios property then the panel driver failed to probe. This was a critial
issue.
With this patch we can not only get rid of 60 interrupt callbacks per second
but also fix the critial issues.

Current implementation of event handling assumes that vblank interrupt is
always called at the right time. It is not true, it can be delayed due to
various reasons. As a result different races can happen. The patch fixes
the issue by using hardware frame counter present in DECON to serialize
vblank and commit completion events.

CRTC event is currently send with next vblank, or instantly in case crtc
is being disabled. This approach usually works, but in corner cases it can
result in premature event generation. Only device driver is able to verify
if the event can be sent. This patch is a first step in that direction - it
moves event handling to the drivers.

qcom_smd_register_edge() is provided by either QCOM_SMD or RPMSG_QCOM_SMD,
and if both of them are disabled, it does nothing.
The check for the PIL drivers however only checks for QCOM_SMD, so it breaks

If avic is not enabled, avic_vm_init() does nothing and returns early.
However, avic_vm_destroy() still tries to destroy what hasn't been created.
The only bad consequence of this now is that avic_vm_destroy() uses
svm_vm_data_hash_lock that hasn't been initialized (and is not meant
to be used at all if avic is not enabled).
Return early from avic_vm_destroy() if avic is not enabled.
It has nothing to destroy.

In the 'commit ebee76f7fa46 ("ath10k: allow setting coverage class")',
it inherits the design and the address offset from ath9k, but the address
is not applicable to QCA6174, which leads to a random crash while doing the
resume() operation, since the set_coverage_class.ops will be called from
ieee80211_reconfig() when resume() (if the wow is not configured).
Fix the incorrect address offset here to avoid the random crash.
Verified on QCA6174/hw3.0 with firmware WLAN.RM.4.4-00022-QCARMSWPZ-2.
kvalo: this also seems to fix a regression with firmware restart.

Both nat_bits cache and free_nid_bitmap cache provide same functionality
as a intermediate cache between free nid cache and disk, but with
different granularity of indicating free nid range, and different
persistence policy. nat_bits cache provides better persistence ability,
and free_nid_bitmap provides better granularity.
In this patch we combine advantage of both caches, so finally policy of
the intermediate cache would be:
- init: load free nid status from nat_bits into free_nid_bitmap
- lookup: scan free_nid_bitmap before load NAT blocks
- update: update free_nid_bitmap in real-time
- persistence: udpate and persist nat_bits in checkpoint
This patch also resolves performance regression reported by lkp-robot.
