Pull ARM SoC fixes from Arnd Bergmann:
"Here are the patches for this week that came as the fallout of the
merge window:
- Two fixes for the NVidia memory controller driver
- multiple defconfig files get patched to turn CONFIG_FB back on
after that is no longer selected by CONFIG_DRM
- ffa and scmpi firmware drivers fixes, mostly addressing compiler
and documentation warnings
- Platform specific fixes for device tree files on ASpeed, Renesas
and NVidia SoC, mostly for recent regressions.
- A workaround for a regression on the USB PHY with devlink when the
usb-nop-xceiv driver is not available until the rootfs is mounted.
- Device tree compiler warnings in Arm Versatile-AB"

This reverts commit 788691464c29455346dc613a3b43c2fb9e5757a4.
It's not clear why, but it causes unexplained problems in entirely
unrelated xfs code. The most likely explanation is some slab
corruption, possibly triggered due to CONFIG_SLUB_DEBUG_ON. See [1].
It ends up having a few other problems too, like build errors on
arch/arc, and Geert reporting it using much more memory on m68k [3] (it
probably does so elsewhere too, but it is probably just more noticeable
on m68k).
The architecture issues (both build and memory use) are likely just
because this change effectively force-enabled STACKDEPOT (along with a
very bad default value for the stackdepot hash size). But together with
the xfs issue, this all smells like "this commit was not ready" to me.

Pull arm64 fixes from Will Deacon:
"The bulk of the diffstat consists of changes to our uaccess routines
so that they fall back to bytewise copying prior to reporting complete
failure when the initial (multi-byte) access faults.
However, the most disappointing change here is that we've had to bump
ARCH_DMA_MINALIGN back to 128 bytes thanks to Qualcomm's "Kryo" CPU,
which ended up in the MSM8996 mobile SoC. Still, at least we're now
aware of this design and one of the hardware designers confirmed the
L2 cacheline size for us.
Summary:
- Fix instrumentation annotations for entry code
- Ensure kernel MTE state is restored correctly on resume from suspend
- Fix MTE fault from new strlen() routine
- Fallback to byte-wise accesses on initial uaccess fault
- Bump Clang requirement for BTI
- Revert ARCH_DMA_MINALIGN back to 128 bytes (shakes fist at Qualcomm)"

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 e590474768f1 ("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.

Pull RCU fixes from Paul McKenney:
- fix regressions induced by a merge-window change in scheduler
semantics, which means that smp_processor_id() can no longer be used
in kthreads using simple affinity to bind themselves to a specific
CPU.
- fix a bug in Tasks Trace RCU that was thought to be strictly
theoretical. However, production workloads have started hitting this,
so these fixes need to be merged sooner rather than later.
- fix a minor printk()-format-mismatch issue introduced during the

The "resets" property is not present on R-Car Gen1 SoCs.
Supporting it would require migrating from renesas,cpg-clocks to
renesas,cpg-mssr.
Reflect this in the DT bindings by removing the global "required:
resets". All SoCs that do have "resets" properties already have
SoC-specific rules making it required.

This reverts commit b7eb335e26a9c7f258c96b3962c283c379d3ede0.
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.

Where it triggered a fault on strlen(key) where key was the filename.
The reason is that filename is a char * to user space, and the histogram
code just blindly dereferenced it, with obvious bad results.
I originally tried to use strncpy_from_user/kernel_nofault() but found
that there's other places that its dereferenced and not worth the effort.
Just do not allow "char *" to act like strings.

Pull fallthrough fixes from Gustavo Silva:
"This fixes many fall-through warnings when building with Clang and
-Wimplicit-fallthrough, and also 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. 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 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
the warning for Clang"
