1d11053dc6 Kbuild: lto: fix module versionings mismatch in GNU make 3.X
When building modules(CONFIG_...=m), I found some of module versions
are incorrect and set to 0.
This can be found in build log for first clean build which shows

WARNING: EXPORT symbol "XXXX" [drivers/XXX/XXX.ko] version generation failed,
symbol will not be versioned.

But in second build(incremental build), the WARNING disappeared and the
module version becomes valid CRC and make someone who want to change
modules without updating kernel image can't insert their modules.

The problematic code is
+	$(foreach n, $(filter-out FORCE,$^),				\
+		$(if $(wildcard $(n).symversions),			\
+			; cat $(n).symversions >> $@.symversions))

For example:
  rm -f fs/notify/built-in.a.symversions    ; rm -f fs/notify/built-in.a; \
llvm-ar cDPrST fs/notify/built-in.a fs/notify/fsnotify.o \
fs/notify/notification.o fs/notify/group.o ...

`foreach n` shows nothing to `cat` into $(n).symversions because
`if $(wildcard $(n).symversions)` return nothing, but actually
they do exist during this line was executed.

-rw-r--r-- 1 root root 168580 Jun 13 19:10 fs/notify/fsnotify.o
-rw-r--r-- 1 root root    111 Jun 13 19:10 fs/notify/fsnotify.o.symversions

The reason is the $(n).symversions are generated at runtime, but
Makefile wildcard function expends and checks the file exist or not
during parsing the Makefile.

Thus fix this by use `test` shell command to check the file
existence in runtime.

d952cfaf0c kbuild: do not suppress Kconfig prompts for silent build
When a new CONFIG option is available, Kbuild shows a prompt to get
the user input.

  $ make
  [ snip ]
  Core Scheduling for SMT (SCHED_CORE) [N/y/?] (NEW)

This is the only interactive place in the build process.

Commit 174a1dcc96 ("kbuild: sink stdout from cmd for silent build")
suppressed Kconfig prompts as well because syncconfig is invoked by
the 'cmd' macro. You cannot notice the fact that Kconfig is waiting
for the user input.

Use 'kecho' to show the equivalent short log without suppressing stdout
from sub-make.

5df99bec21 scripts/setlocalversion: fix a bug when LOCALVERSION is empty
The commit 042da426f8 ("scripts/setlocalversion: simplify the short
version part") reduces indentation. Unfortunately, it also changes behavior
in a subtle way - if the user has empty "LOCALVERSION" variable, the plus
sign is appended to the kernel version. It wasn't appended before.

This patch reverts to the old behavior - we append the plus sign only if
the LOCALVERSION variable is not set.

  - 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.

ae14c63a9f Revert "mm/slub: use stackdepot to save stack trace in objects"
This reverts commit 788691464c.

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

ARM: multi_v7_defconfig: Make NOP_USB_XCEIV driver built-in
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.

ARM: configs: Update u8500_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.

Arm FF-A fixes for v5.14

A small set of fixes:
- adding check for presence of probe while registering the driver to
  prevent NULL pointer access
- dropping the duplicate check as the driver core already takes care of it
- fixing possible ffa_linux_errmap buffer overflow and
- fixing kernel-doc warning for comment style

50d8d7e19c dt-bindings: display: renesas,du: Make resets optional on R-Car H1
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.

d936eb2387 Revert "Makefile: Enable -Wimplicit-fallthrough for Clang"
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.

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.

e9338abf0e fallthrough fixes for Clang for 5.14-rc2
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!
