Non-migratable faults that require devmem incorrectly jump to the 'out'
label, which squashes the error code intended to be returned to the
upper layers. Fix this by returning -EACCES instead.

proper locking is in place. Also ensure that OA registers are whitelisted
when the first OA stream is open and de-whitelisted after the last OA

Whitelist OA registers on stream open and de-whitelist on stream
close/release. Whitelisting is only done when 'stream->sample' is
true. 'stream->sample' is only true when (a) xe_observation_paranoid is set
to false by system admin, or (b) the process is perfmon_capable(). This
therefore enforces the OA register whitelisting security requirements.

Now we can save OA whitelisting nonpriv registers to register save/restore
lists. OA nonpriv registers are saved to both hwe->oa_sr as well as
hwe->reg_sr.
During probe, resume and gt-reset flows KMD will apply hwe->reg_sr,
ensuring OA registers are de-whitelisted after these events. For
engine-reset, hwe->reg_sr is registered with GuC and GuC will apply these
registers, ensuring OA registers are de-whitelisted after engine resets.
hwe->oa_sr is used for whitelisting or de-whitelisting OA registers during
OA operation, by toggling the 'deny' bit on oa stream open/close.

Clang < 21 treats const-qualified compound literals at function scope as
having static storage duration, which requires all initializer elements
to be compile-time constants. When xe_hw_engine.c initializes a local
struct xe_rtp_table_sr using XE_RTP_TABLE_SR(), the compound literals in
XE_RTP_TABLE_SR end up containing runtime values (e.g. blit_cctl_val
derived from gt->mocs.uc_index), triggering:
xe_hw_engine.c:361: error: initializer element is not a compile-time constant
xe_hw_engine.c:416: error: initializer element is not a compile-time constant
ARRAY_SIZE() cannot be used as a replacement because it expands through
__must_be_array() -> __BUILD_BUG_ON_ZERO_MSG() -> _Static_assert inside
sizeof(struct{}), which clang < 21 also rejects in the same context.
Replace ARRAY_SIZE() with an open-coded sizeof(arr)/sizeof(elem) in
XE_RTP_TABLE_SR and XE_RTP_TABLE to avoid both issues.

We currently have a mixture of styles for our RTP tables with respect of
how we define the number of entries:
* xe_rtp_process_to_sr() expects to receive the number of entries as
arguments;
* xe_rtp_process() expects the array to have a sentinel at the end of
the array;
* in xe_rtp_test.c, even though xe_rtp_process_to_sr() does not
require a sentinel value, we need to rely on that technique to be
able to count xe_rtp_entry_sr entries because simply using
ARRAY_SIZE() is not possible.
The style used by xe_rtp_process_to_sr() makes it hard to share the
tables with other compilation units (e.g. kunit tests), since the number
of entries is calculated with ARRAY_SIZE(), which is done at compile
time.
Since we use the size of the tables to create some bitmasks, using a
sentinel style doesn't seem great either.
A way to reconcile things into a single style is to have a struct type
that would hold the entries array and the number of entries. Since we
have xe_rtp_entry and xe_rtp_entry_sr, we would have one type for each.
The advantage of the proposed approach is that now we have a nice way to
share the tables directly to kunit tests with information about their
size.
v6:
- Removed sentinels that are not needed
v5:
- Removed added code from conflict resolution issues
v4:
- Removed conflicts with main branch
v3:
- No changes
v2:
- Add compatibility with new xe_rtp_table_sr format for
"bad-mcr-reg-forced-to-regular" and
"bad-regular-reg-forced-to-mcr"

The page-table walk framework may pass a NULL *child pointer for
unpopulated entries. xe_pt_zap_ptes_entry() called container_of(*child)
before checking for NULL, then dereferenced the result, causing a crash.
Move the container_of() call after a NULL guard, so the function returns
early instead of proceeding with an invalid pointer. XE_WARN_ON is kept
to help root cause the issue, but we now bail instead of crashing the
driver.

A kernel job that exhausts its recovery attempts called
xe_device_declare_wedged() directly from guc_exec_queue_timedout_job(),
while the handler still owned the timed-out job and the queue scheduler
(sched = &q->guc->sched, stopped at the top of the handler).
In the default wedged mode (XE_WEDGED_MODE_UPON_CRITICAL_ERROR),
xe_device_declare_wedged() takes the destructive path in
xe_guc_submit_wedge(): guc_submit_reset_prepare(), xe_guc_submit_stop()
- which calls guc_exec_queue_stop() on every queue, including this one -
softreset and pause-abort. That tears submission down, signals the
in-flight fences and restarts the schedulers. This is the correct
behaviour when the wedge originates outside the TDR, but not when the
TDR itself triggers it: every queue should be torn down except the one
the TDR is currently operating on, which it still owns.
Control then returned to the handler, which kept using the now stale job
and scheduler:
xe_sched_job_set_error(job, err);
drm_sched_for_each_pending_job(tmp_job, &sched->base, NULL)
xe_sched_job_set_error(to_xe_sched_job(tmp_job), -ECANCELED);
drm_sched_for_each_pending_job() warns because the scheduler is no
longer stopped (WARN_ON(!drm_sched_is_stopped())) and the iteration then
dereferences a freed job, faulting on the slab poison:
Oops: general protection fault ... 0x6b6b6b6b6b6b6c3b
RIP: guc_exec_queue_timedout_job+...
Defer the wedge until the handler has finished operating on the queue,
right before returning DRM_GPU_SCHED_STAT_NO_HANG, so the teardown no
longer races with this handler's use of @q.

Commit 44f9200699 ("Input: gscps2 - use guard notation when
acquiring spinlock") moved the receive loop into gscps2_read_data()
and gscps2_report_data().
While moving the code, it preserved the writes to
buffer[ps2port->append], but omitted the following producer index
update from the original loop:
ps2port->append = (ps2port->append + 1) & BUFFER_SIZE;
As a result, append never advances. Since gscps2_report_data() only
reports bytes while act != append, the receive buffer always appears
empty and no keyboard or mouse data reaches the serio core.
Restore the omitted index update.

Some touchpads (e.g. ThinkPad T14 Gen 1) have buggy firmware that reports
a register descriptor structure size that is too small for the number of
registers it claims to have in the presence map. The remaining bytes in
the structure are 0, which with the new strict bounds checking causes the
parser to fail with -EIO, aborting the device probe.
Tolerate such short reads by dropping the remaining (unparseable or
0-size) registers from the list instead of failing the probe,
preventing the driver from trying to use them.

The register descriptor presence register is a packet register, which
means its bytes share a single RMI address. It does not occupy
consecutive addresses, and the register structure that follows it
is located at the next RMI address (presence_address + 1), not
(presence_address + presence_size).
Revert the incorrect address calculation introduced in commit
a98518e724.

When BAR_PEER_SPAD and BAR_CONFIG share one PCI BAR, the module teardown
path ends up calling pci_iounmap() on the same iomem with some offset,
which is unnecessary and triggers a kernel warning like the following:

Merge tag 'v7.2-rc-part2-smb3-server-fixes' of git://git.samba.org/ksmbd
Pull smb server updates from Steve French:
"This is mostly a correctness and compatibility update for ksmbd's
SMB2/3 lease, oplock, durable handle, compound request, CREATE,
rename, stream and share-mode handling.
A large part of the series fixes cases found by smbtorture where ksmbd
diverged from the SMB2/3 protocol requirements.
The main changes are:
- Rework SMB2 lease state handling so lease state is shared per
ClientGuid/LeaseKey across opens, with better validation of lease
create contexts, ACK handling, epochs, break-in-progress reporting,
v2 lease notification routing, and chained lease breaks
- Fix several oplock break corner cases, including ACK validation,
timeout downgrade behavior, level-II break handling on unlink,
share-conflict lease breaks, and read-control/stat-open behavior
- Fix durable handle behavior around delete-on-close, stale
reconnects, reconnect context parsing, oplock/lease break
invalidation, and durable v2 AppInstanceId replacement
- Fix compound request handling so related commands propagate failed
statuses correctly, preserve response framing across chained
errors, keep compound FIDs across READ/WRITE/FLUSH, and send
interim STATUS_PENDING where clients expect cancellable compound
I/O
- Tighten CREATE and stream semantics, including create attribute
validation, allocation size reporting, explicit create security
descriptors, unnamed DATA stream handling, stream directory
validation, and stream delete sharing against the base file
- Fix rename and metadata behavior, including parent directory
sharing checks, denying directory rename with open children, and
preserving SMB ChangeTime across rename for open handles
- Fix two important safety issues: a multichannel byte-range lock
list owner race that could lead to use-after-free, and an NTLMv2
session key update before authentication proof validation
- Fix a concurrent SMB2 NEGOTIATE preauth use-after-free, a UBSAN
warning in compression capability parsing, a false hung-task
warning in the durable handle scavenger, endian debug logging,
Smatch indentation warnings, and kernel-doc warnings
- Increase the default SMB3 transaction size from 1MB to 4MB to
better match modern read/write negotiation and improve sequential
I/O behavior"

info->var, a framebuffer's current mode, is expected to have a matching
entry in info->modelist. var_to_display() relies on this and treats a
failed fb_match_mode() as "This should not happen". fb_set_var() keeps it
true by adding the mode to the list on every change, and
do_register_framebuffer() does the same at registration.
store_modes() replaces the modelist from userspace. fb_new_modelist()
validates the new modes but does not check that info->var still has a
match. It relies on fbcon_new_modelist() to re-point consoles, but that
only handles consoles mapped to the framebuffer. With fbcon unbound there
are none, so info->var is left describing a mode that is no longer in the
list.
A later console takeover runs var_to_display(), where fb_match_mode()
returns NULL and leaves fb_display[i].mode NULL. fbcon_switch() passes it
to display_to_var(), and fb_videomode_to_var() dereferences the NULL mode.
Keep the current mode in the list in fb_new_modelist(), the same way
fb_set_var() does.
