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.

"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.

Pull slab updates from Vlastimil Babka:
"This time it's just a bunch of smaller cleanups and fixes for SLAB and
SLUB:
- Make it possible to use kmem_cache_alloc_bulk() early in boot when
interrupts are not yet enabled, as code doing that started to
appear via new maple tree users (Thomas Gleixner)
- Fix debugfs-related memory leak in SLUB (Greg Kroah-Hartman)
- Use the standard idiom to get head page of folio (SeongJae Park)
- Simplify and inline is_debug_pagealloc_cache() in SLAB (lvqian)
- Remove unused variable in SLAB (Gou Hao)"
* tag 'slab-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
mm, slab/slub: Ensure kmem_cache_alloc_bulk() is available early
mm/slub: fix memory leak with using debugfs_lookup()
mm/slab.c: cleanup is_debug_pagealloc_cache()
mm/sl{a,u}b: fix wrong usages of folio_page() for getting head pages
mm/slab: remove unused slab_early_init
Pull kprobes updates from Masami Hiramatsu:
- Skip negative return code check for snprintf in eprobe
- Add recursive call test cases for kprobe unit test
- Add 'char' type to probe events to show it as the character instead
of value
- Update kselftest kprobe-event testcase to ignore '__pfx_' symbols
- Fix kselftest to check filter on eprobe event correctly
- Add filter on eprobe to the README file in tracefs
- Fix optprobes to check whether there is 'under unoptimizing' optprobe
when optimizing another kprobe correctly
- Fix optprobe to check whether there is 'under unoptimizing' optprobe
when fetching the original instruction correctly
- Fix optprobe to free 'forcibly unoptimized' optprobe correctly
* tag 'probes-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing/eprobe: no need to check for negative ret value for snprintf
test_kprobes: Add recursed kprobe test case
tracing/probe: add a char type to show the character value of traced arguments
selftests/ftrace: Fix probepoint testcase to ignore __pfx_* symbols
selftests/ftrace: Fix eprobe syntax test case to check filter support
tracing/eprobe: Fix to add filter on eprobe description in README file
x86/kprobes: Fix arch_check_optimized_kprobe check within optimized_kprobe range
x86/kprobes: Fix __recover_optprobed_insn check optimizing logic
kprobes: Fix to handle forcibly unoptimized kprobes on freeing_list
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_ext+0x64/0xa0 [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.
Fixes: 9ed7bfc795 ("sctp: fix memory leak in sctp_stream_outq_migrate()")

IPQ5332 has the APSS clock controller utilizing the same register space
as the APCS, so provide access to the APSS utilizing a child device like
other IPQ chipsets.
Like IPQ6018, the same controller and driver is used, so utilize IPQ6018
match data for IPQ5332.

Add the mailbox compatible for the IPQ5332 SoC.
Since the IPQ5332 mailbox is compatible with the IPQ6018, lets create the
fallback to ipq6018 compatible, so that we don't bloat the of_device_id
table in the driver.

MSM8996 also has the clock-related part of the APCS mailbox device.
Follow the usual pattern and create a child device to handle these
clocks.
