The syscall entry points to the kernel defined by SYSCALL_DEFINEx()
and COMPAT_SYSCALL_DEFINEx() should only be called from userspace
through kernel entry points, but not from the kernel itself. This
will allow cleanups and optimizations to the entry paths *and* to
the parts of the kernel code which currently need to pretend to be
userspace in order to make use of syscalls.

dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
dmaengine: rcar-dmac: fix max_chunk_size for R-Car Gen3
On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.
With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

One notable fix to properly advertise our support for a new firmware feature,
caused by two series conflicting semantically but not textually.
There's a new ioctl for the new ocxl driver, which is not a fix, but needed to
complete the userspace API and good to have before the driver is in a released
kernel.
Finally three minor selftest fixes, and a fix for intermittent build failures
for some obscure platforms, caused by a missing make dependency.

Lastly there is a deadlock fix around runtime suspend for secondary

There was a deadlock between one thread trying to wait for a workqueue
job to finish in the runtime suspend path, and the workqueue job it
was waiting for in turn waiting for a runtime_get_sync to return.
The fixes avoids it by not doing the runtime sync in the workqueue as
then we always wait for all those tasks to complete before we runtime
suspend"

A single change (and associated DT binding update) to allow the address
of the MIPS Cluster Power Controller (CPC) to be chosen by DT, which
allows SMP to work on generic MIPS kernels where the bootloader hasn't
configured the CPC address (i.e. the new Ranchu platform).

which allows SMP to work on generic MIPS kernels where the bootloader

A test_and_{}_bit() operation fails if the value of the bit is such that
the modification does not take place. For example, if test_and_set_bit()
returns 1. In these cases, follow the behaviour of cmpxchg and allow the
operation to be unordered. This also applies to test_and_set_bit_lock()
if the lock is found to be be taken already.

Due to the old method has already been marked as deprecated in binding
doc, so obviously it's better to update the example to new bindings
as well.
