Fix the warnings by deleting the unused items.
One item, the "nerrs" variable in vsdo_restorer.c's main(), is unused

That result is also unused right now, so another option would be to
delete it entirely, but this way, main() also gets fixed. It was missing

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...the following build failure occurs in selftests/x86:
clang: error: cannot specify -o when generating multiple output files
This happens because, although gcc doesn't complain if you invoke it
like this:
gcc file1.c header2.h
...clang won't accept that form--it rejects the .h file(s). Also, the
above approach is inaccurate anyway, because file.c includes header2.h
in this case, and the inclusion of header2.h on the invocation is an
artifact of the Makefile's desire to maintain dependencies.
In Makefiles of this type, a better way to do it is to use Makefile
dependencies to trigger the appropriate incremental rebuilds, and
separately use file lists (see EXTRA_FILES in this commit) to track what
to pass to the compiler.
This commit splits those concepts up, by setting up both EXTRA_FILES and
the Makefile dependencies with a single call to the new Makefile
function extra-files.
That fixes the build failure, while still providing the correct
dependencies in all cases.

bw_report is only needed for selecting the correct value from the

is always set to "reads". The value is then checked in resctrl_val()
using validate_bw_report_request() that besides validating the input,
assumes it can mutate the string which is questionable programming
practice.
Simplify handling bw_report:
- Convert validate_bw_report_request() into get_bw_report_type() that
inputs and returns const char *. Use NULL to indicate error.
- Validate the report types inside measure_mem_bw(), not in
resctrl_val().

'bm_pid' and 'ppid' are global variables. As they are used by different

local variables.
The scope of those variables can still be reduced into resctrl_val.c
only. As PARENT_EXIT() macro is using 'ppid', make it a function in
resctrl_val.c and pass ppid to it as an argument because it is easier
to understand than using the global variable directly.

variable which helps to make the call signatures of measure_vals() and

For MBM/MBA tests, measure_vals() calls get_mem_bw_imc() that performs
the measurement over a duration of sleep(1) call. The memory bandwidth
numbers from IMC are derived over this duration. The resctrl FS derived
memory bandwidth, however, is calculated inside measure_vals() and only
takes delta between the previous value and the current one which
besides the actual test, also samples inter-test noise.
Rework the logic in measure_vals() and get_mem_bw_imc() such that the
resctrl FS memory bandwidth section covers much shorter duration
closely matching that of the IMC perf counters to improve measurement
accuracy.
For the second read after rewind() to return a fresh value, also
newline has to be consumed by the fscanf().

gcc defaults to silence (off) for the following warnings, but clang
defaults to the opposite. The warnings are not useful for the kernel
itself, which is why they have remained disabled in gcc for the main
kernel build. And it is only due to including kernel data structures in
the selftests, that we get the warnings from clang.
-Waddress-of-packed-member
-Wgnu-variable-sized-type-not-at-end
In other words, the warnings are not unique to the selftests: there is
nothing that the selftests' code does that triggers these warnings,
other than the act of including the kernel's data structures. Therefore,
silence them for the clang builds as well.
This eliminates warnings for the net/ and user_events/ kselftest

all, resulting in none of the usual CFLAGS being passed. That can
be seen in the output above, the only flag passed to the compiler is
-Wno-error.
Fix it by dropping the conditional setting of CFLAGS in flags.mk.
Instead always set CFLAGS, but also append USERCFLAGS if they are set.
Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk
is included by multiple Makefiles (to support partial builds), causing
CFLAGS to be appended to multiple times. Additionally that would place
the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS
couldn't override the standard flags. Being able to override the
standard flags is desirable, for example for adding -Wno-error.
With the fix in place, the CFLAGS are set correctly, including the
USERCFLAGS:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...
gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"'
-I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error
cache_shape.c ...

DTS for Nokia N900 incorrectly specifies "active high" polarity for
the reset line, while the chip documentation actually specifies it as
"active low". In the past the driver fudged gpiod API and inverted
the logic internally, but it was changed in d0d89493bf.
