The usage of usb-nop-xceiv PHY on Raspberry Pi boards with BCM283x has
been a "regression source" a lot of times. The last case is breakage of
USB mass storage boot has been commit e590474768 ("driver core: Set
fw_devlink=on by default") for multi_v7_defconfig. As long as
NOP_USB_XCEIV is configured as module, the dwc2 USB driver defer probing
endlessly and prevent booting from USB mass storage device. So make
the driver built-in as in bcm2835_defconfig and arm64/defconfig.

The platform lost the framebuffer due to a commit solving a
circular dependency in v5.14-rc1, so add it back in by explicitly
selecting the framebuffer.
The U8500 has also gained a few systems using touchscreens from
Cypress, Melfas and Zinitix so add these at the same time as
we're updating the defconfig anyway.

This updates the Versatile Express defconfig for the changes
in the v5.14-rc1 kernel:
- The Framebuffer CONFIG_FB needs to be explicitly selected
or we don't get any framebuffer anymore. DRM has stopped to
select FB because of circular dependency.
- CONFIG_CMA options were moved around.
- CONFIG_MODULES options were moved around.
- CONFIG_CRYPTO_HW was moved around.

Reflect this in the DT bindings by removing the global "required:

This reverts commit b7eb335e26.
It turns out that the problem with the clang -Wimplicit-fallthrough
warning is not about the kernel source code, but about clang itself, and
that the warning is unusable until clang fixes its broken ways.
In particular, when you enable this warning for clang, you not only get
warnings about implicit fallthroughs. You also get this:
warning: fallthrough annotation in unreachable code [-Wimplicit-fallthrough]
which is completely broken becasue it
(a) doesn't even tell you where the problem is (seriously: no line
numbers, no filename, no nothing).
(b) is fundamentally broken anyway, because there are perfectly valid
reasons to have a fallthrough statement even if it turns out that
it can perhaps not be reached.
In the kernel, an example of that second case is code in the scheduler:
switch (state) {
case cpuset:
if (IS_ENABLED(CONFIG_CPUSETS)) {
cpuset_cpus_allowed_fallback(p);
state = possible;
break;
}
fallthrough;
case possible:
where if CONFIG_CPUSETS is enabled you actually never hit the
fallthrough case at all. But that in no way makes the fallthrough
wrong.
So the warning is completely broken, and enabling it for clang is a very
bad idea.
In the meantime, we can keep the gcc option enabled, and make the gcc
build use
-Wimplicit-fallthrough=5
which means that we will at least continue to require a proper
fallthrough statement, and that gcc won't silently accept the magic
comment versions. Because gcc does this all correctly, and while the odd
"=5" part is kind of obscure, it's documented in [1]:
"-Wimplicit-fallthrough=5 doesn’t recognize any comments as
fallthrough comments, only attributes disable the warning"
so if clang ever fixes its bad behavior we can try enabling it there again.

Hi Linus,
Please, pull the following patches that fix many fall-through
warnings when building with Clang and -Wimplicit-fallthrough.
This pull-request also contains the patch for Makefile that enables
-Wimplicit-fallthrough for Clang, globally.
It's also important to notice that since we have adopted the use of
the pseudo-keyword macro fallthrough; we also want to avoid having
more /* fall through */ comments being introduced. Notice that contrary
to GCC, Clang doesn't recognize any comments as implicit fall-through
markings when the -Wimplicit-fallthrough option is enabled. So, in
order to avoid having more comments being introduced, we have to use
the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang,
will cause a warning in case a code comment is intended to be used
as a fall-through marking. The patch for Makefile also enforces this.
We had almost 4,000 of these issues for Clang in the beginning,
and there might be a couple more out there when building some
architectures with certain configurations. However, with the
recent fixes I think we are in good shape and it is now possible
to enable -Wimplicit-fallthrough for Clang. :)
Thanks!

ASan reports several memory leaks running:
# perf test "88: Check open filename arg using perf trace + vfs_getname"
The third of these leaks is related to evsel->priv fields of sycalls
never being deallocated.
This patch adds the function evlist__free_syscall_tp_fields which
iterates over all evsels in evlist, matching syscalls, and calling the
missing frees.
This new function is called at the end of trace__run, right before
calling evlist__delete.

ASan reports several memory leaks running:
# perf test "88: Check open filename arg using perf trace + vfs_getname"
The second of these leaks is caused by the arg_fmt field of syscall not
being deallocated.
This patch adds a new function syscall__exit which is called on all
syscalls.table entries in trace__exit, which will free the arg_fmt
field.

ASan reports several memory leaks running:
# perf test "88: Check open filename arg using perf trace + vfs_getname"
The first of these leaks is related to struct trace fields never being
deallocated.
This patch adds the function trace__exit, which is called at the end of
cmd_trace, replacing the existing deallocation, which is now moved
inside the new function.
This function deallocates:
- ev_qualifier
- ev_qualifier_ids.entries
- syscalls.table
- sctbl
- perfconfig_events

ASan reports several memory leaks while running:
# perf test "82: Use vfs_getname probe to get syscall args filenames"
Two of these are caused by some refcounts not being decreased on
perf-script exit, namely script.threads and script.cpus.
This patch adds the missing __put calls in a new perf_script__exit
function, which is called at the end of cmd_script.
This patch concludes the fixes of all remaining memory leaks in perf

ASan reports several memory leaks when running:
# perf test "82: Use vfs_getname probe to get syscall args filenames"
many of which are related to session->tevent.
This patch will solve this problem, then next patch will fix the
remaining memory leaks in 'perf script'.
This bug is due to a missing deallocation of the trace_event data
strutures.
This patch adds the missing trace_event__cleanup() in
perf_session__delete().
