Remove the 'preferred_cstates' module parameter as it is not really useful.
The parameter currently only affects Alder Lake, where it controls C1/C1E
preference, with C1E being the default. The parameter does not support any
other platform. For example, Meteor Lake has a similar C1/C1E limitation,
but the parameter does not support Meteor Lake. This indicates that the
parameter is not very useful.
Generally, independent C1 and C1E are important for server platforms where
low latency is key. However, they are not as important for client platforms,
like Alder Lake, where C1E providing better energy savings is generally
preferred.
The parameter was originally introduced for Sapphire Rapids Xeon:
da0e58c038 intel_idle: add 'preferred_cstates' module argument
Later it was added to Alder Lake:
d1cf8bbfed ("intel_idle: Add AlderLake support")
But it was removed from Sapphire Rapids when firmware fixed the C1/C1E
limitation:
1548fac47a ("intel_idle: make SPR C1 and C1E be independent")
So Alder Lake is the only platform left where this parameter has any effect.
Remove this parameter to simplify the driver and reduce maintenance burden.

A bug was reported about an infinite recursion caused by tracing the rcu
events with the kernel stack trace trigger enabled. The stack trace code
called back into RCU which then called the stack trace again.
Expand the ftrace recursion protection to add a set of bits to protect
events from recursion. Each bit represents the context that the event is
in (normal, softirq, interrupt and NMI).
Have the stack trace code use the interrupt context to protect against
recursion.
Note, the bug showed an issue in both the RCU code as well as the tracing
stacktrace code. This only handles the tracing stack trace side of the
bug. The RCU fix will be handled separately.

When user resize all trace ring buffer through file 'buffer_size_kb',
then in ring_buffer_resize(), kernel allocates buffer pages for each
cpu in a loop.
If the kernel preemption model is PREEMPT_NONE and there are many cpus
and there are many buffer pages to be freed, it may not give up cpu
for a long time and finally cause a softlockup.
To avoid it, call cond_resched() after each cpu buffer free as Commit
f6bd2c9248 ("ring-buffer: Avoid softlockup in ring_buffer_resize()")
does.

Some compute SoCs support additional operation modes, extending the
existing set of USB3/safe/DP-alt-mode.
The firmware performs all the necessary handshakes for
us and there is no room for error on that level (i.e. the sequences
will match what happens on Windows).
The trade-off with that approach is that the received notifications
trim some of the PDO/EUDO data (particularly the cable/plug parts),
offering a set of similar-in-nature-but-not-the-same indicators.
In an attempt to remedy this, I reconstructed some of it, so that the
connected mux/retimer drivers can continue to behave as expected.
Add support for parsing the aforementioned data coming from PMIC_GLINK
and passing it on to the various Type-C components.

`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data
into `ihid->rawbuf`.
The former can come from the userspace in the hidraw driver and is only
bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set
`max_buffer_size` field of `struct hid_ll_driver` which we do not).
The latter has size determined at runtime by the maximum size of
different report types you could receive on any particular device and
can be a much smaller value.
Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`.
The impact is low since access to hidraw devices requires root.

If no kunitconfig_paths are passed to LinuxSourceTree() it falls back to
DEFAULT_KUNITCONFIG_PATH. This resolution only works when the current
working directory is the root of the source tree. This works by chance
when running the full testsuite through the default unittest runner, as
some tests will change the current working directory as a side-effect of
'kunit.main()'. When running a single testcase or using pytest, which
resets the working directory for each test, this assumption breaks.
Explicitly specify an empty kunitconfig for the affected tests.

Running the KUnit testsuite through pytest fails, as the function
test_data_path() is recognized as a test function. Its execution fails
as pytest tries to resolve the 'path' argument as a fixture which does
not exist.
Rename the function, so the helper function is not incorrectly
recognized as a test function.

"snps,tx_de_emphasis" is supposed to be a u8, not a u32. Since it is big
endian, 0 will be read rather than 1. The DWC3 Linux driver simply ORs
the value if "snps,tx_de_emphasis_quirk" is set, so the 2 properties
have no effect. (The driver doesn't clear the field either which is
another problem).
"snps,gctl-reset-quirk" is not documented nor used in the driver, so
drop it as well.
