c440adfbe3 tracing/probes: Support BTF based data structure field access

b1d1e90490 tracing/probes: Support BTF argument on module functions
Since the btf returned from bpf_get_btf_vmlinux() only covers functions in
the vmlinux, BTF argument is not available on the functions in the modules.
Use bpf_find_btf_id() instead of bpf_get_btf_vmlinux()+btf_find_name_kind()
so that BTF argument can find the correct struct btf and btf_type in it.
With this fix, fprobe events can use `$arg*` on module functions as below

 # grep nf_log_ip_packet /proc/kallsyms
ffffffffa0005c00 t nf_log_ip_packet	[nf_log_syslog]
ffffffffa0005bf0 t __pfx_nf_log_ip_packet	[nf_log_syslog]
 # echo 'f nf_log_ip_packet $arg*' > dynamic_events
 # cat dynamic_events
f:fprobes/nf_log_ip_packet__entry nf_log_ip_packet net=net pf=pf hooknum=hooknum skb=skb in=in out=out loginfo=loginfo prefix=prefix

To support the module's btf which is removable, the struct btf needs to be
ref-counted. So this also records the btf in the traceprobe_parse_context
and returns the refcount when the parse has done.

f8bbf8b990 tracing/eprobe: Iterate trace_eprobe directly
Refer to the description in [1], we can skip "container_of()" following
"list_for_each_entry()" by using "list_for_each_entry()" with
"struct trace_eprobe" and "tp.list".

Also, this patch defines "for_each_trace_eprobe_tp" to simplify the code
of the same logic.

2b6aa6610d platform/x86: lenovo-ymc: Only bind on machines with a convertible DMI chassis-type
The lenovo-ymc driver is causing the keyboard + touchpad to stop working
on some regular laptop models such as the Lenovo ThinkBook 13s G2 ITL 20V9.

The problem is that there are YMC WMI GUID methods in the ACPI tables
of these laptops, despite them not being Yogas and lenovo-ymc loading
causes libinput to see a SW_TABLET_MODE switch with state 1.

This in turn causes libinput to ignore events from the builtin keyboard
and touchpad, since it filters those out for a Yoga in tablet mode.

Similar issues with false-positive SW_TABLET_MODE=1 reporting have
been seen with the intel-hid driver.

Copy the intel-hid driver approach to fix this and only bind to the WMI
device on machines where the DMI chassis-type indicates the machine
is a convertible.

Add a 'force' module parameter to allow overriding the chassis-type check
so that users can easily test if the YMC interface works on models which
report an unexpected chassis-type.

c8afaa1b0f locking: remove spin_lock_prefetch
The only remaining consumer is new_inode, where it showed up in 2001 as
commit c37fa164f793 ("v2.4.9.9 -> v2.4.9.10") in a historical repo [1]
with a changelog which does not mention it.

Since then the line got only touched up to keep compiling.

While it may have been of benefit back in the day, it is guaranteed to
at best not get in the way in the multicore setting -- as the code
performs *a lot* of work between the prefetch and actual lock acquire,
any contention means the cacheline is already invalid by the time the
routine calls spin_lock().  It adds spurious traffic, for short.

On top of it prefetch is notoriously tricky to use for single-threaded
purposes, making it questionable from the get go.

As such, remove it.

I admit upfront I did not see value in benchmarking this change, but I
can do it if that is deemed appropriate.

Removal from new_inode and of the entire thing are in the same patch as
requested by Linus, so whatever weird looks can be directed at that guy.

Commit

  522b1d6921 ("x86/cpu/amd: Add a Zenbleed fix")

provided a fix for the Zen2 VZEROUPPER data corruption bug affecting
a range of CPU models, but the AMD Custom APU 0405 found on SteamDeck
was not listed, although it is clearly affected by the vulnerability.

Add this CPU variant to the Zenbleed erratum list, in order to
unconditionally enable the fallback fix until a proper microcode update
is available.

33f83d13de gpio: ws16c48: Fix off-by-one error in WS16C48 resource region extent
The WinSystems WS16C48 I/O address region spans offsets 0x0 through 0xA,
which is a total of 11 bytes. Fix the WS16C48_EXTENT define to the
correct value of 11 so that access to necessary device registers is
properly requested in the ws16c48_probe() callback by the
devm_request_region() function call.

I fat-fingered the name of cpu_show_gds(). Usually, I'd rebase but since
those are extraordinary embargoed times, the commit above was already
pulled into another tree so no no.

Therefore, fix it ontop.

a7a7dabb5d nvme: core: don't hold rcu read lock in nvme_ns_chr_uring_cmd_iopoll
Now nvme_ns_chr_uring_cmd_iopoll() has switched to request based io
polling, and the associated NS is guaranteed to be live in case of
io polling, so request is guaranteed to be valid because blk-mq uses
pre-allocated request pool.

Remove the rcu read lock in nvme_ns_chr_uring_cmd_iopoll(), which
isn't needed any more after switching to request based io polling.

Fix "BUG: sleeping function called from invalid context" because
set_page_dirty_lock() from blk_rq_unmap_user() may sleep.

Fixes: 585079b6e4 ("nvme: wire up async polling for io passthrough commands")
