dev_kfree_skb() is aliased to consume_skb().
When a driver is dropping a packet by calling dev_kfree_skb_any()
we should propagate the drop reason instead of pretending
the packet was consumed.
Note: Now we have enum skb_drop_reason we could remove
enum skb_free_reason (for linux-6.4)
v2: added an unlikely(), suggested by Yunsheng Lin.

Pull MM updates from Andrew Morton:
- Daniel Verkamp has contributed a memfd series ("mm/memfd: add
F_SEAL_EXEC") which permits the setting of the memfd execute bit at
memfd creation time, with the option of sealing the state of the X
bit.
- Peter Xu adds a patch series ("mm/hugetlb: Make huge_pte_offset()
thread-safe for pmd unshare") which addresses a rare race condition
related to PMD unsharing.

Moola, Sidhartha Kumar and Lorenzo Stoakes
- Johannes Weiner has a series ("mm: push down lock_page_memcg()")
which does perform some memcg maintenance and cleanup work.

"mm/damon/core: implement damos filter".
These filters provide users with finer-grained control over DAMOS's
actions. SeongJae has also done some DAMON cleanup work.
- Kairui Song adds a series ("Clean up and fixes for swap").
- Vernon Yang contributed the series "Clean up and refinement for maple
tree".

- Christoph Hellwig has removed the generic_writepages() library
function in the series "remove generic_writepages".

support for memory-deny-write-execute (MDWE)".
- Waiman Long did some kmemleak cleanup and bugfixing in the series
"mm/kmemleak: Simplify kmemleak_cond_resched() & fix UAF".
- T.J. Alumbaugh has contributed some MGLRU cleanup work in his series

statistics reporting, mainly by presenting the statistics on a
per-node basis. See the series "Introduce per NUMA node memory error
statistics".

Each probe has an instance of process_fetch_insn respectively,
but they have something in common.
This patch aims to extract the common part into
process_common_fetch_insn which can be shared by each probe,
and they only need to focus on their special cases.

There are 6 function definitions in trace_probe_tmpl.h, they are:
1, fetch_store_strlen
2, fetch_store_string
3, fetch_store_strlen_user
4, fetch_store_string_user
5, probe_mem_read
6, probe_mem_read_user
Every C file which includes trace_probe_tmpl.h has to implement them,
otherwise it gets warnings and errors. However, some of them are identical,
like kprobe and eprobe, as a result, there is a lot redundant code in those
2 files.
This patch would like to provide default behaviors for those functions
which kprobe and eprobe can share by just including trace_probe_kernel.h
with trace_probe_tmpl.h together.
It removes redundant code, increases readability, and more importantly,
makes it easier to introduce a new feature based on trace probe
(it's possible).

This adds support for the 256-byte internal RAM. There are two windows
which can be used to access this RAM: 64 bytes at 0x40 (the "standard"
address space) and 128 bytes at 0x80 (the "alternate" address space). We
use the standard address space because it is also accessible over SPI
(if such a port is ever done). We are limited to 32-byte reads for SMBus
compatibility, so there's no advantage to using the alternate address
space.
There are some reserved bits in the EXTRAM register, and the datasheet
doesn't say what to do with them. I've opted to skip a read/modify/write
and just write the whole thing. If this driver is ever converted to
regmap, this would be a good place to use regmap_update_bits.

APUs before Raven didn't support s0ix. As we just relieved some
of the safety checks for s0ix to improve power consumption on
APUs that support it but that are missing BIOS support a new
blind spot was introduced that a user could "try" to run s0ix.
Plug this hole so that if users try to run s0ix on anything older
than Raven it will just skip suspend of the GPU.

GFX v11 changes RB_BACKEND_DISABLE related registers
from per SA to global ones. The approach to query active
rb bitmap needs to be changed accordingly. Query per
SE setting returns wrong active RB bitmap especially
in the case when some of SA are disabled. With the new
approach, driver will generate the active rb bitmap
based on active SA bitmap and global active RB bitmap.

Pull modules updates from Luis Chamberlain:
"Nothing exciting at all for modules for v6.3.
The biggest change is just the change of INSTALL_MOD_DIR from "extra"
to "updates" which I found lingered for ages for no good reason while
testing the CXL mock driver [0].
The CXL mock driver has no kconfig integration and requires building
an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash.
All this can obviously be fixed by integrating kconfig semantics into
such test module, however that's not desirable by the maintainer, and
so sensible defaults must be used to ensure a default "make
modules_install" will suffice for most distros which do not have a
file like /etc/depmod.d/dist.conf with something like `search updates
extra built-in`.
Since most distros rely on kmod and since its inception the "updates"
directory is always in the search path it makes more sense to use that
than the "extra" which only *some* RH based systems rely on.
All this stuff has been on linux-next for a while"

With this refcnt added in sctp_stream_priorities, we don't need to
traverse all streams to check if the prio is used by other streams
when freeing one stream's prio in sctp_sched_prio_free_sid(). This
can avoid a nested loop (up to 65535 * 65535), which may cause a
stuck as Ying reported:
watchdog: BUG: soft lockup - CPU#23 stuck for 26s! [ksoftirqd/23:136]
Call Trace:
<TASK>
sctp_sched_prio_free_sid+0xab/0x100 [sctp]

sctp_stream_free+0x31/0x50 [sctp]
sctp_association_free+0xa5/0x200 [sctp]
Note that it doesn't need to use refcount_t type for this counter,
as its accessing is always protected under the sock lock.
v1->v2:
- add a check in sctp_sched_prio_set to avoid the possible prio_head
refcnt overflow.
