tracer_tracing_is_on() checks whether record_disabled is not zero. This
checks both the record_disabled counter and the RB_BUFFER_OFF flag.
Reading the source it looks like this function should only check for
the RB_BUFFER_OFF flag. Therefore use ring_buffer_record_is_set_on().
This fixes spurious fails in the 'test for function traceon/off triggers'
test from the ftrace testsuite when the system is under load.

Commit a8b9cf62ad ("ftrace: Fix DIRECT_CALLS to use SAVE_REGS by
default") attempted to fix an issue with direct trampolines on x86, see
its description for details. However, it wrongly referenced the
HAVE_DYNAMIC_FTRACE_WITH_REGS config option and the problem is still
present.
Add the missing "CONFIG_" prefix for the logic to work as intended.

NVM Express TP4167 provides a way for controllers to report a relaxed
execution constraint. Specifically, it notifies of exclusivity for IO
vs. admin commands instead of grouping these together. If set, then we
don't need to freeze IO in order to execute that admin command. The
freezing distrupts IO processes, so it's nice to avoid that if the
controller tells us it's not necessary.

The 'phandle-array' type is a bit ambiguous. It can be either just an

the latter and needs to be constrained to a single entry with a phandle and

The RAPL framework uses CPU hotplug locking to protect the rapl_packages
list and rp->lead_cpu to guarantee that
1. the RAPL package device is not unprobed and freed
2. the cached rp->lead_cpu is always valid
for operations like powercap sysfs accesses.
Current RAPL APIs assume being called from CPU hotplug callbacks which
hold the CPU hotplug lock, but TPMI RAPL driver invokes the APIs in the
driver's .probe() function without acquiring the CPU hotplug lock.
Fix the problem by providing both locked and lockless versions of RAPL
APIs.

A NULL pointer dereference is triggered when probing the MMIO RAPL
driver on platforms with CPU ID not listed in intel_rapl_common CPU
model list.
This is because the intel_rapl_common module still probes on such
platforms even if 'defaults_msr' is not set after commit 1488ac990a
("powercap: intel_rapl: Allow probing without CPUID match"). Thus the
MMIO RAPL rp->priv->defaults is NULL when registering to RAPL framework.
Fix the problem by adding sanity check to ensure rp->priv->rapl_defaults
is always valid.

Change these all to actually expect a void pointer to be passed, which
matches the caller.

clang-16 complains about a control flow integrity (kcfi) violation
casting between incompatible pointers:
drivers/block/floppy.c:2001:11: error: cast from 'void (*)(void)' to 'done_f' (aka 'void (*)(int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

Just add another empty function with the correct prototype as a
workaround.
The warning is for code that was added before the start of the normal
git history, but I tracked it done to an early change in the reconstructed
linux-history.git.

There was a change in the mxs-dma engine that uses a new custom flag.
The change was not applied to the mxs spi driver.
This results in chipselect being deasserted too early.
This fixes the chipselect problem by using the new flag in the mxs-spi
driver.

PMD Global Transmit Disable bit should be cleared for normal operation.
This should be HW default, however I found that on Asus RT-AX89X that uses
AQR113C PHY and firmware 5.4 this bit is set by default.
With this bit set the AQR cannot achieve a link with its link-partner and
it took me multiple hours of digging through the vendor GPL source to find
this out, so lets always clear this bit during .config_init() to avoid a
situation like this in the future.

Sometimes gt_pm live_rc6_manual selftest fails due to no power being
measured for the rc6 disabled period. Therefore increasing the rc6 disable
period from 250ms to 1000ms to rule out such sporadic failure.
