drm/xe: Convert GT stats to per-cpu counters
Current GT statistics use atomic64_t counters. Atomic operations incur a global coherency penalty. Transition to dynamic per-cpu counters using alloc_percpu(). This allows stats to be incremented via this_cpu_add(), which compiles to a single non-locking instruction. This approach keeps the hot-path updates local to the CPU, avoiding expensive cross-core cache invalidation traffic. Use for_each_possible_cpu() during aggregation and clear operations to ensure data consistency across CPU hotplug events.

scsi: lpfc: Properly set WC for DPP mapping
Using set_memory_wc() to enable write-combining for the DPP portion of
the MMIO mapping is wrong as set_memory_*() is meant to operate on RAM
only, not MMIO mappings. In fact, as used currently triggers a BUG_ON()
with enabled CONFIG_DEBUG_VIRTUAL.
Simply map the DPP region separately and in addition to the already
existing mappings, avoiding any possible negative side effects for
these.

macvlan: observe an RCU grace period in macvlan_common_newlink() error path
valis reported that a race condition still happens after my prior patch.
macvlan_common_newlink() might have made @dev visible before
detecting an error, and its caller will directly call free_netdev(dev).
We must respect an RCU period, either in macvlan or the core networking
stack.
After adding a temporary mdelay(1000) in macvlan_forward_source_one()
to open the race window, valis repro was:
ip link add p1 type veth peer p2
ip link set address 00:00:00:00:00:20 dev p1

selftests: tc_actions: don't dump 2MB of \0 to stdout
Since we started running selftests in NIPA we have been seeing
tc_actions.sh generate a soft lockup warning on ~20% of the runs.
On the pre-netdev foundation setup it was actually a missed irq
splat from the console. Now it's either that or a lockup.
I initially suspected a socket locking issue since the test
is exercising local loopback with act_mirred.
After hours of staring at this I noticed in strace that ncat
when -o $file is specified _both_ saves the output to the file
and still prints it to stdout. Because the file being sent
is constructed with:
dd conv=sparse status=none if=/dev/zero bs=1M count=2 of=$mirred
^^^^^^^^^
the data printed is all \0. Most terminals don't display nul
characters (and neither does vng output capture save them).
But QEMU's serial console still has to poke them thru which
is very slow and causes the lockup (if the file is >600kB).
Replace the '-o $file' with '> $file'. This speeds the test up
from 2m20s to 18s on debug kernels, and prevents the warnings.

ping: annotate data-races in ping_lookup()
isk->inet_num, isk->inet_rcv_saddr and sk->sk_bound_dev_if

The race on isk->inet_rcv_saddr is probably coming from IPv6 support,
but does not deserve a specific backport.

drm/pagemap: pass pagemap_addr by reference
Passing a structure by value into a function is sometimes problematic,
for a number of reasons. Of of these is a warning from the 32-bit arm
compiler:
drivers/gpu/drm/drm_gpusvm.c: In function '__drm_gpusvm_unmap_pages':
drivers/gpu/drm/drm_gpusvm.c:1152:33: note: parameter passing for argument of type 'struct drm_pagemap_addr' changed in GCC 9.1
1152 | dpagemap->ops->device_unmap(dpagemap,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1153 | dev, *addr);
| ~~~~~~~~~~~
This particular problem is harmless since we are not mixing compiler versions
inside of the compiler. However, passing this by reference avoids the warning
along with providing slightly better calling conventions as it avoids an
extra copy on the stack.

drm/xe/xe2_hpg: Fix handling of Wa_14019988906 & Wa_14019877138
The PSS_CHICKEN register has been part of the RCS engine's LRC since it was first introduced in Xe_LP. That means that any workarounds that adjust its value (such as Wa_14019988906 and Wa_14019877138) need to be implemented in the lrc_was[] table so that they become part of the default LRC from which all subsequent LRCs are copied. Although these workarounds were implemented correctly on most platforms, they were incorrectly placed on the engine_was[] table for Xe2_HPG. Move the workarounds to the proper lrc_was[] table and switch the 'xe_rtp_match_first_render_or_compute' rule to specifically match the RCS since that's the engine whose LRC manages the register.

drm/xe/mmio: Avoid double-adjust in 64-bit reads
xe_mmio_read64_2x32() was adjusting register addresses and then calling xe_mmio_read32(), which applies the adjustment again. This may shift accesses twice if adj_offset < adj_limit. There is no issue currently, as for media gt, adj_offset > adj_limit, so the 2nd adjust will be a no-op. But it may not work in future. To fix it, replace the adjusted-address comparison with a direct sanity check that ensures the MMIO address adjustment cutoff never falls within the 8-byte range of a 64-bit register. And let xe_mmio_read32() handle address translation. v2: rewrite the sanity check in a more natural way. (Matt) v3: Add Fixes tag. (Jani) Fixes: |

drm/xe: Add bounds check on pat_index to prevent OOB kernel read in madvise
When user provides a bogus pat_index value through the madvise IOCTL, the xe_pat_index_get_coh_mode() function performs an array access without validating bounds. This allows a malicious user to trigger an out-of-bounds kernel read from the xe->pat.table array. The vulnerability exists because the validation in madvise_args_are_sane() directly calls xe_pat_index_get_coh_mode(xe, args->pat_index.val) without first checking if pat_index is within [0, xe->pat.n_entries). Although xe_pat_index_get_coh_mode() has a WARN_ON to catch this in debug builds, it still performs the unsafe array access in production kernels. v2(Matthew Auld) - Using array_index_nospec() to mitigate spectre attacks when the value is used v3(Matthew Auld) - Put the declarations at the start of the block Fixes: |

drm/xe/pf: Fix sysfs initialization
In case of devm_add_action_or_reset() failure the provided cleanup action will be run immediately on the not yet initialized kobject.

Also make this cleanup registration a part of the create helper to fix another mistake, as in the loop we were wrongly passing parent kobject while registering cleanup action, and this resulted in some undetected leaks.

drm/xe/hwmon: Prevent unintended VRAM channel creation
Remove the unnecessary VRAM channel entry introduced in xe_hwmon_channel.
Without this, adding any new hwmon channel causes extra VRAM channel
to appear. This remained unnoticed earlier because VRAM was the
final xe hwmon channel.
v2: Use MAX_VRAM_CHANNELS with in_range() instead of
CHANNEL_VRAM_N_MAX. (Raag)

TTY / Serial driver updates for 7.0-rc1
Here is the small amount of tty and serial driver updates for 7.0-rc1.
Nothing major in here at all, just some driver updates and minor tweaks
and cleanups including:
- sh-sci serial driver updates
- 8250 driver updates
- attempt to make the tty ports have their own workqueue, but was
reverted after testing found it to have problems on some platforms.
This will probably come back for 7.1 after it has been reworked and
resubmitted
- other tiny tty driver changes

Pull more io_uring updates from Jens Axboe:
"This is a mix of cleanups and fixes. No major fixes in here, just a
bunch of little fixes. Some of them marked for stable as it fixes
behavioral issues
- Fix an issue with SOCKET_URING_OP_SETSOCKOPT for netlink sockets,
due to a too restrictive check on it having an ioctl handler
- Remove a redundant SQPOLL check in ring creation
- Kill dead accounting for zero-copy send, which doesn't use ->buf
or ->len post the initial setup
- Fix missing clamp of the allocation hint, which could cause
allocations to fall outside of the range the application asked
for. Still within the allowed limits.
- Fix for IORING_OP_PIPE's handling of direct descriptors
- Tweak to the API for the newly added BPF filters, making them
more future proof in terms of how applications deal with them
- A few fixes for zcrx, fixing a few error handling conditions
- Fix for zcrx request flag checking
- Add support for querying the zcrx page size
- Improve the NO_SQARRAY static branch inc/dec, avoiding busy
conditions causing too much traffic
- Various little cleanups"

drm/panic: depends on PRINTK
drm_panic uses kmsg_dump_register() to register its panic handler, so it won't work if CONFIG_PRINTK is not enabled. Let's not pretend it could work without PRINTK, and depends explicitly on it.

spi: spidev: fix lock inversion between spi_lock and buf_lock
The spidev driver previously used two mutexes, spi_lock and buf_lock, but acquired them in different orders depending on the code path: write()/read(): buf_lock -> spi_lock ioctl(): spi_lock -> buf_lock This AB-BA locking pattern triggers lockdep warnings and can cause real deadlocks: WARNING: possible circular locking dependency detected spidev_ioctl() -> mutex_lock(&spidev->buf_lock) spidev_sync_write() -> mutex_lock(&spidev->spi_lock) *** DEADLOCK *** The issue is reproducible with a simple userspace program that performs write() and SPI_IOC_WR_MAX_SPEED_HZ ioctl() calls from separate threads on the same spidev file descriptor. Fix this by simplifying the locking model and removing the lock inversion entirely. spidev_sync() no longer performs any locking, and all callers serialize access using spi_lock. buf_lock is removed since its functionality is fully covered by spi_lock, eliminating the possibility of lock ordering issues. This removes the lock inversion and prevents deadlocks without changing userspace ABI or behaviour.
