Use the same frequency test for all clk_csr value lookups (clock
rate > table rate). This has the side effect that the standard rate
table results in the divider being used for the maximum frequency
for the divider rather than the next higher divider. This still
allows MDC to meet the IEE 802.3 specification, but at a rate closer
to 2.5MHz for these frequencies.

Convert the MDC clock divisor selection to tabular format.
Note that there is a change for 300MHz, but this is not a problem,
as the MDC clock remains within the useable ranges, which are:
STMMAC_CSR_500_800M /324 1.54 - 2.47MHz
STMMAC_CSR_300_500M /204 1.47 - 2.45MHz
STMMAC_CSR_250_300M /124 2.02 - 2.42MHz
STMMAC_CSR_150_250M /102 1.47 - 2.45MHz
STMMAC_CSR_100_150M /62 1.61 - 2.42MHz
STMMAC_CSR_60_100M /42 1.43 - 2.38MHz
STMMAC_CSR_35_60M /26 1.35 - 2.31MHz
STMMAC_CSR_20_35M /16 1.25 - 2.19MHz
Thus, with the change of divisor for exactly 300MHz, MDC temporarily
changes from 2.42MHz to 1.47MHz for the sake of consistency.
The databook does not specify whether the frequency limits for the
CSR divider are inclusive or exclusive.

Driver core holds a reference to the USB interface and its parent USB
device while the interface is bound to a driver and there is no need to
take additional references unless the structures are needed after
disconnect.
This driver takes a reference to the USB device during probe but does
not to release it on probe failures.
Drop the redundant device reference to fix the leak, reduce cargo
culting, make it easier to spot drivers where an extra reference is
needed, and reduce the risk of further memory leaks.

The large chunks test does a probe run of iou-zcrx before it runs the
actual test. After the probe run finishes, the context will still exist
until the deferred io_uring teardown. When running iou-zcrx the second
time, io_uring_register_ifq() can return -EEXIST due to the existence of
the old context.
The fix is simple: wait for the context teardown using the new
mp_clear_wait() utility before running the second instance of iou-zcrx.

Once a task exits it has its state set to TASK_DEAD and then it is
removed from the cgroup it belonged to. The last step happens on the task
gets out of its last schedule() invocation and is delayed on PREEMPT_RT
due to locking constraints.
As a result it is possible to receive a pid via waitpid() of a task
which is still listed in cgroup.procs for the cgroup it belonged
to. This is something that systemd does not expect and as a result it
waits for its exit until a time out occurs.
This can also be reproduced on !PREEMPT_RT kernel with a significant
delay in do_exit() after exit_notify().
Hide the task from the output which have PF_EXITING set which is done
before the parent is notified. Keeping zombies with live threads
shouldn't break anything (suggested by Tejun).

Multiple events can be enabled on the kernel command line via a comma
separator. But if the are specified one at a time, then only the last
event is enabled. This is because the event names are saved in a temporary
buffer, and each call by the init cmdline code will reset that buffer.
This also affects names in the boot config file, as it may call the
callback multiple times with an example of:
kernel.trace_event = ":mod:rproc_qcom_common", ":mod:qrtr", ":mod:qcom_aoss"
Change the cmdline callback function to append a comma and the next value
if the temporary buffer already has content.
