Note that runtime is also used in the pm context, so it is confusing to
use the same name to denote run time of the drm client. Use a more
appropriate name for the client utilization.
While at it, drop the incorrect multi-lrc comment in the helper

When powering on a null_blk device that is not already on, the return
value ret that is initialized to be count is reused to check the return
value of null_add_dev(), leading to nullb_device_power_store() to return
null_add_dev() return value (0 on success) instead of "count".
So make sure to set ret to be equal to count when there are no errors.

In order to be able to run gpu jobs from reclaim context,
move job creation (where allocation takes place) out of the
struct xe_migrate::job_mutex, and prime that mutex as reclaim
tainted.
Jobs that may need to run from reclaim context include
CCS metadata extraction at shrinking time.

Pre-allocate but don't initialize fences at xe_sched_job_create(),
and initialize / arm them instead at xe_sched_job_arm(). This
makes it possible to move xe_sched_job_create() with its memory
allocation out of any lock that is required for fence
initialization, and that may not allow memory allocation under it.
Replaces the struct dma_fence_array for parallell jobs with a
struct dma_fence_chain, since the former doesn't allow
a split-up between allocation and initialization.
v2:
- Rebase.
- Don't always use the first lrc when initializing parallel
lrc fences.
- Use dma_fence_chain_contained() to access the lrc fences.
v4:
- Add an assert that job->lrc_seqno == fence->seqno.

Since sometimes a lock is required to initialize a seqno fence,
and it might be desirable not to hold that lock while performing
memory allocations, split the lrc seqno fence creation up into an
allocation phase and an initialization phase.
Since lrc seqno fences under the hood are hw_fences, do the same
for these and remove the xe_hw_fence_create() function since it
is not used anymore.

We have seen an influx of syzkaller reports where a BPF program attached to
a tracepoint triggers a locking rule violation by performing a map_delete
on a sockmap/sockhash.
We don't intend to support this artificial use scenario. Extend the
existing verifier allowed-program-type check for updating sockmap/sockhash
to also cover deleting from a map.
From now on only BPF programs which were previously allowed to update
sockmap/sockhash can delete from these map types.

We recently upgraded the view of ESR_EL2 to 64bit, in keeping with
the requirements of the architecture.
However, the AArch32 emulation code was left unaudited, and the
(already dodgy) code that triages whether a trap is spurious or not
(because the condition code failed) broke in a subtle way:
If ESR_EL2.ISS2 is ever non-zero (unlikely, but hey, this is the ARM
architecture we're talking about), the hack that tests the top bits
of ESR_EL2.EC will break in an interesting way.
Instead, use kvm_vcpu_trap_get_class() to obtain the EC, and list
all the possible ECs that can fail a condition code check.
While we're at it, add SMC32 to the list, as it is explicitly listed
as being allowed to trap despite failing a condition code check (as
described in the HCR_EL2.TSC documentation).

When userspace writes to one of the core registers, we make
sure to narrow the corresponding GPRs if PSTATE indicates
an AArch32 context.
The code tries to check whether the context is EL0 or EL1 so
that it narrows the correct registers. But it does so by checking
the full PSTATE instead of PSTATE.M.
As a consequence, and if we are restoring an AArch32 EL0 context
in a 64bit guest, and that PSTATE has *any* bit set outside of
PSTATE.M, we narrow *all* registers instead of only the first 15,
destroying the 64bit state.
Obviously, this is not something the guest is likely to enjoy.
Correctly masking PSTATE to only evaluate PSTATE.M fixes it.

An async dio write to a sparse file can generate a lot of extents
and when we unlink this file (using rm), the kernel can be busy in umapping
and freeing those extents as part of transaction processing.
Similarly xfs reflink remapping path can also iterate over a million
extent entries in xfs_reflink_remap_blocks().
Since we can busy loop in these two functions, so let's add cond_resched()
to avoid softlockup messages like these.

Bunch of stuff in intel_color_check() needs to look at both the
old and new crtc states. Currently we do that by digging the
full atomic state via the crtc_state->state pointer. That thing
is a total footgun if I ever saw one, as it's only valid during
specific parts of the atomic flow. A lot of people have been
bitten by this thing in the past when trying to use it after
it's no longer valid.
Take a small step towards elimination of the footgun by not
using it in the inte_color_check(). Instead we plumb in the
entire atomic state all the way from the top.

There's a problem in 9p's interaction with netfslib whereby a crash occurs
because the 9p_fid structs get forcibly destroyed during client teardown
(without paying attention to their refcounts) before netfslib has finished
with them. However, it's not a simple case of deferring the clunking that
p9_fid_put() does as that requires the p9_client record to still be
present.
The problem is that netfslib has to unlock pages and clear the IN_PROGRESS
flag before destroying the objects involved - including the fid - and, in
any case, nothing checks to see if writeback completed barring looking at
the page flags.
Fix this by keeping a count of outstanding I/O requests (of any type) and
waiting for it to quiesce during inode eviction.

gcc assumes that 'sizeof(*args) + size' can overflow, which would result
in the problem.
The problem is not new, only it is now no longer a warning but an error
since W=1 has been enabled for the drm subsystem and since Werror is
enabled for test builds.
Rearrange arithmetic and use check_add_overflow() for validating the
allocation size to avoid the overflow. While at it, split assignments
out of if conditions.

mitigation become invalid
When a trip point becomes invalid after being crossed on the way up,
it is involved in a mitigation episode that needs to be adjusted to
compensate for the trip going away.
For this reason, introduce thermal_zone_trip_down() as a wrapper
around thermal_trip_crossed() and make thermal_zone_set_trip_temp()
call it if the new temperature of the trip at hand is equal to
THERMAL_TEMP_INVALID and it has been crossed on the way up to trigger
all of the necessary adjustments in user space, the thermal debug
code and the zone governor.

trips, but it overlooked the fact that a trip may become invalid during
a mitigation eposide involving it, in which case its statistics should
still be reported.
For this reason, remove the invalid trip temperature check from the
main loop in tze_seq_show().
The trips that have never been valid will still be skipped after this
change because there are no statistics to report for them.

The temperature and hysteresis of a trip point may change during a

current temperature and hysteresis.

LED Select (LED_SEL) bit in the LED General Purpose IO Configuration
register is used to determine the functionality of external LED pins
(Speed Indicator, Link and Activity Indicator, Full Duplex Link
Indicator). The default value for this bit is 0 when no EEPROM is
present. If a EEPROM is present, the default value is the value of the
LED Select bit in the Configuration Flags of the EEPROM. A USB Reset or
Lite Reset (LRST) will cause this bit to be restored to the image value
last loaded from EEPROM, or to be set to 0 if no EEPROM is present.
While configuring the dual purpose GPIO/LED pins to LED outputs in the
LED General Purpose IO Configuration register, the LED_SEL bit is changed
as 0 and resulting the configured value from the EEPROM is cleared. The
issue is fixed by using read-modify-write approach.
