184caba444 arm64: defconfig: Enable TI K3 M4 remoteproc driver
Some K3 platform devices (AM64x, AM62x) have a Cortex M4 core. Build
the M4 remote proc driver as a module for these platforms.

Similar to the TI K3-AM62x SoC commit ce27f7f9e3
("arm64: dts: ti: k3-am62-wakeup: Configure ti-sysc for wkup_uart0"),
The devices in the wkup domain are capable of waking up the system from
suspend. We can configure the wkup domain devices in a generic way using
the ti-sysc interconnect target module driver like we have done with the
earlier TI SoCs.

As ti-sysc manages the SYSCONFIG related registers independent of the
child hardware device, the wake-up configuration is also set even if
wkup_uart0 is reserved by sysfw.

The wkup_uart0 device has interconnect target module register mapping like
dra7 wkup uart. There is a 1 MB interconnect target range with one uart IP
block in the target module. The power domain and clock affects the whole
interconnect target module.

Note we change the functional clock name to follow the ti-sysc binding
and use "fck" instead of "fclk".

Also note that we need to disable the target module reset as noted by
Markus. Otherwise the sysfw using wkup_uart0 can get confused on some
devices leading to boot time issues such as mbox timeouts.

eb2008a8fc arm64: dts: ti: k3-am625-beagleplay: Fix DP83TD510E reset time
The reset deassert time for the DP83TD510E is incorrectly set to
60000us, while the datasheet states that the minimum time required
after an hard reset is 30us (while 60ms is the time required for the
Power-On Reset after supply stabilization). The error probably arose
from the two timings being indicated by the same symbol (T2).

Lower the required time to 35us, aligning it to the value required for
the PHY to complete the reset AND to be able to accept the RMII master
clock. This saves ~60ms on boot if the MDIO driver is built-in.

e2b6918043 arm64: dts: ti: k3-am642-hummingboard-t: Convert overlay to board dts
SolidRun HummingBoard-T has two options for M.2 connector, supporting
either PCI-E or USB-3.1 Gen 1 - depending on configuration of a mux
on the serdes lane.
The required configurations in device-tree were modeled as overlays.

The USB-3.1 overlay uses /delete-property/ to unset a boolean property
on the usb controller limiting it to USB-2.0 by default.
Overlays can not delete a property from the base dtb, therefore this
overlay is at this time useless.

Convert both overlays into full dts by including the base board dts.
While the pcie overlay was functional, both are converted for a
consistent user experience when selecting between the two mutually
exclusive configurations.

80f130bfad dm thin: make get_first_thin use rcu-safe list first function
The documentation in rculist.h explains the absence of list_empty_rcu()
and cautions programmers against relying on a list_empty() ->
list_first() sequence in RCU safe code.  This is because each of these
functions performs its own READ_ONCE() of the list head.  This can lead
to a situation where the list_empty() sees a valid list entry, but the
subsequent list_first() sees a different view of list head state after a
modification.

In the case of dm-thin, this author had a production box crash from a GP
fault in the process_deferred_bios path.  This function saw a valid list
head in get_first_thin() but when it subsequently dereferenced that and
turned it into a thin_c, it got the inside of the struct pool, since the
list was now empty and referring to itself.  The kernel on which this
occurred printed both a warning about a refcount_t being saturated, and
a UBSAN error for an out-of-bounds cpuid access in the queued spinlock,
prior to the fault itself.  When the resulting kdump was examined, it
was possible to see another thread patiently waiting in thin_dtr's
synchronize_rcu.

The thin_dtr call managed to pull the thin_c out of the active thins
list (and have it be the last entry in the active_thins list) at just
the wrong moment which lead to this crash.

Fortunately, the fix here is straight forward.  Switch get_first_thin()
function to use list_first_or_null_rcu() which performs just a single
READ_ONCE() and returns NULL if the list is already empty.

This was run against the devicemapper test suite's thin-provisioning
suites for delete and suspend and no regressions were observed.

064737920b arm64: Filter out SVE hwcaps when FEAT_SVE isn't implemented
The hwcaps code that exposes SVE features to userspace only
considers ID_AA64ZFR0_EL1, while this is only valid when
ID_AA64PFR0_EL1.SVE advertises that SVE is actually supported.

The expectations are that when ID_AA64PFR0_EL1.SVE is 0, the
ID_AA64ZFR0_EL1 register is also 0. So far, so good.

Things become a bit more interesting if the HW implements SME.
In this case, a few ID_AA64ZFR0_EL1 fields indicate *SME*
features. And these fields overlap with their SVE interpretations.
But the architecture says that the SME and SVE feature sets must
match, so we're still hunky-dory.

This goes wrong if the HW implements SME, but not SVE. In this
case, we end-up advertising some SVE features to userspace, even
if the HW has none. That's because we never consider whether SVE
is actually implemented. Oh well.

Fix it by restricting all SVE capabilities to ID_AA64PFR0_EL1.SVE
being non-zero. The HWCAPS documentation is amended to reflect the
actually checks performed by the kernel.

ASoC: renesas: rz-ssi: Add a check for negative sample_space
My static checker rule complains about this code.  The concern is that
if "sample_space" is negative then the "sample_space >= runtime->channels"
condition will not work as intended because it will be type promoted to a
high unsigned int value.

strm->fifo_sample_size is SSI_FIFO_DEPTH (32).  The SSIFSR_TDC_MASK is
0x3f.  Without any further context it does seem like a reasonable warning
and it can't hurt to add a check for negatives.

ASoC: soc-card: remove card check
only snd_soc_card_set_bias_level() and snd_soc_card_set_bias_level_post()
are checking "card" in the function, like below

	int snd_soc_card_set_bias_level(...)
	{
		...
=>		if (card && card->xxx)
			ret = card->xxxx(...);
		...
	}

But it should already have been an error if "card" was NULL.
remove "card" NULL check here. Otherwise it will get waring on
smatch without this patch. This is prepare for error check cleanup.

Test a more realistic usage pattern, and one with heavy contention, in order to

This test has several threads in a tight loop acquiring a mutex, modifying some
shared data, and then releasing the mutex. At the end we check if the data is
consistent.
