The PCI core already updates the primary, secondary and subordinate bus
number registers fields of the Type 1 header.
Thus, remove the redundant code from the nwl_pcie_bridge_init().

commit ef8dd01538 ("genirq/msi: Make interrupt allocation less
convoluted"), reworked the code so that the x86 specific quirk for affinity
setting of non-maskable PCI/MSI interrupts is not longer activated if
necessary.
This could be solved by restoring the original logic in the core MSI code,
but after a deeper analysis it turned out that the quirk flag is not
required at all.
The quirk is only required when the PCI/MSI device cannot mask the MSI
interrupts, which in turn also prevents reservation mode from being enabled
for the affected interrupt.
This allows ot remove the NOMASK quirk bit completely as msi_set_affinity()
can instead check whether reservation mode is enabled for the interrupt,
which gives exactly the same answer.
Even in the momentary non-existing case that the reservation mode would be
not set for a maskable MSI interrupt this would not cause any harm as it
just would cause msi_set_affinity() to go needlessly through the
functionaly equivalent slow path, which works perfectly fine with maskable
interrupts as well.
Rework msi_set_affinity() to query the reservation mode and remove all
NOMASK quirk logic from the core code.

Merge tag 'nf-next-23-10-25' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next
Pablo Neira Ayuso says:
====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next. Mostly
nf_tables updates with two patches for connlabel and br_netfilter.
1) Rename function name to perform on-demand GC for rbtree elements,
and replace async GC in rbtree by sync GC. Patches from Florian Westphal.
2) Use commit_mutex for NFT_MSG_GETRULE_RESET to ensure that two
concurrent threads invoking this command do not underrun stateful
objects. Patches from Phil Sutter.
3) Use single hook to deal with IP and ARP packets in br_netfilter.
Patch from Florian Westphal.
4) Use atomic_t in netns->connlabel use counter instead of using a
spinlock, also patch from Florian.
5) Cleanups for stateful objects infrastructure in nf_tables.
Patches from Phil Sutter.
6) Flush path uses opaque set element offered by the iterator, instead of
calling pipapo_deactivate() which looks up for it again.
7) Set backend .flush interface always succeeds, make it return void
instead.
8) Add struct nft_elem_priv placeholder structure and use it by replacing
void * to pass opaque set element representation from backend to frontend
which defeats compiler type checks.
9) Shrink memory consumption of set element transactions, by reducing
struct nft_trans_elem object size and reducing stack memory usage.
10) Use struct nft_elem_priv also for set backend .insert operation too.
11) Carry reset flag in nft_set_dump_ctx structure, instead of passing it
as a function argument, from Phil Sutter.

gsm_cleanup_mux() cleans up the gsm by closing all DLCIs, stopping all
timers, removing the virtual tty devices and clearing the data queues.
This procedure, however, may cause subsequent changes of the virtual modem
status lines of a DLCI. More data is being added the outgoing data queue
and the deleted kick timer is restarted to handle this. At this point many
resources have already been removed by the cleanup procedure. Thus, a
kernel panic occurs.
Fix this by proving in gsm_modem_update() that the cleanup procedure has
not been started and the mux is still alive.
Note that writing to a virtual tty is already protected by checks against
the DLCI specific connection state.

hid_connect() will call hid_pidff_init() which does
hid_device_io_start() leading to an "io already started" warning.
To fix this call hid_device_io_stop() before calling hid_connect(),
stopping IO means that connect events may be lost while hid_connect()
runs, re-enable IO and move the hidpp_connect_event() work queuing
after the hid_connect().
Note re-enabling IO is also necessary for the g920_get_config()
call later during hidpp_probe().

Move sequence of masking and unmasking global interrupts from buttress
interrupt handler to generic one that handles both VPUIP and BTRS
interrupts. Unmasking global interrupts will re-trigger MSI for any
pending interrupts.
Lack of this sequence will cause the driver to miss any
VPUIP interrupt that comes after reading VPU_37XX_HOST_SS_ICB_STATUS_0
and before clearing all active interrupt sources.

The get_task_exe_file() function locks the given task with task_lock()
which when used inside audit_exe_compare() can cause deadlocks on
systems that generate audit records when the task_lock() is held. We
resolve this problem with two changes: ignoring those cases where the
task being audited is not the current task, and changing our approach
to obtaining the executable file struct to not require task_lock().
With the intent of the audit exe filter being to filter on audit events
generated by processes started by the specified executable, it makes
sense that we would only want to use the exe filter on audit records
associated with the currently executing process, e.g. @current. If
we are asked to filter records using a non-@current task_struct we can
safely ignore the exe filter without negatively impacting the admin's
expectations for the exe filter.
Knowing that we only have to worry about filtering the currently
executing task in audit_exe_compare() we can do away with the
task_lock() and call get_mm_exe_file() with @current->mm directly.

But the WARN_ON() only has:

Where to match the comment (and what it should actually do) is:
