On large systems, the refscale printk() rate can overrun the file system's
ability to accept console log messages. This commit therefore uses the
new verbose_batched module parameter to rate-limit some of the higher-rate
printk() calls.

The bash "eval" command enables Bobby Tables attacks, which might not
be a concern in torture testing by themselves, but one could imagine
these combined with a cut-and-paste attack. This commit therefore gets
rid of them. This comes at a price in terms of bash quoting not working
nicely, so the "--bootargs" argument lists are now passed to torture_one
via a bash-variable side channel. This might be a bit ugly, but it will
also allow torture.sh to grow its own --bootargs parameter.
While in the area, add proper header comments for the bash functions.

Although tailoring a specific set of kvm.sh runs has served rcutorture
testing well over many years, it requires a relatively distraction-free
environment, which is not always available. This commit therefore
adds a prototype torture.sh script that by default tortures pretty much
everything the rcutorture scripting is designed to torture, and which
can be given command-line arguments to take a more focused approach.

Currently, if a scenario is repeated as in "--configs '4*TREE01'",
the Kconfig analysis is performed for each occurrance (four times in
this example) and each analysis places the exact same data into the
exact same files. This is not really an issue in this repetition-four
example, but it can needlessly consume tens of seconds of wallclock time
for something like "--config '128*TINY01'".
This commit therefore does Kconfig analysis only once per set of
repeats of a given scenario, courtesy of the "sort -u" command and an
automatically generated awk script.
While in the area, this commit also wordsmiths a comment.

Normally, kvm-recheck.sh is run from kvm.sh, which provides the
TORTURE_TRUST_MAKE environment variable that, if a non-empty string,
indicates that the --trust-make command-line parameter has been passed
to kvm.sh. If there was no --trust-make, kvm-recheck.sh insists
that the Make.out file contain at least one "CC" command. Thus, when
kvm-recheck.sh is run standalone to evaluate a prior --trust-make run,
it will incorrectly insist that a proper kernel build did not happen.
This commit therefore causes kvm-recheck.sh to also search the "log"
file in the top-level results directory for the string "--trust-make".

Commit 757055ae8ded ("init/console: Use ttynull as a fallback when
there is no console") results in the string "Warning: Failed to add
ttynull console. No stdin, stdout, and stderr for the init process!"
appearing on the console, which the rcutorture scripting interprets as
a warning, which causes every rcutorture run to be flagged. However,
the rcutorture init process never attempts to do any I/O, and thus does
not care that it has no stdin, stdout, or stderr.
This commit therefore causes the rcutorture scripting to ignore this
message.

This commit changes the "STOP" file that is used to cleanly halt a running
rcutorture run to "STOP.1" because no scenario directory will ever end
with ".1". If there really was a scenario named "STOP", its directories
would instead be named "STOP", "STOP.2", "STOP.3", and so on. While in
the area, the commit also changes the kernel-run-time checks for this
file to look directly in the directory above $resdir, thus avoiding the
need to pass the TORTURE_STOPFILE environment variable to remote systems.
While in the area, move the STOP.1 file to the top-level directory
covering all of the scenarios.

When all of the remote systems have the same number of CPUs, one
approach is to use one "--buildonly" run and one "--dryrun sched" run,
and then distributing the batches out one per remote system. However,
the output of "--dryrun sched" is not made for parsing, so this commit
adds a "--dryrun batches" that provides the same information in easily
parsed form.

By default, the "panic" kernel parameter is zero, which causes the kernel
to loop indefinitely after a panic(). The rcutorture scripting will
eventually kill the corresponding qemu process, but only after waiting
for the full run duration plus a few minutes. This works, but delays
notifying the developer of the failure.
This commit therefore causes the rcutorture scripting to pass the
"panic=-1" kernel parameter, which caused the kernel to instead
unceremoniously shut down immediately. This in turn causes qemu to
terminate, so that if all of the runs in a given batch panic(), the
rcutorture scripting can immediately proceed to the next batch.

Currently, passing something like "--kconfig CONFIG_NR_CPUS=2" to kvm.sh
has no effect on scenario scheduling. For scenarios that do not specify
the number of CPUs, this can result in kvm.sh wastefully scheduling only
one scenario at a time even when the --kconfig argument would allow
a number to be run concurrently. This commit therefore makes kvm.sh
consider the --kconfig arguments when scheduling scenarios across the
available CPUs.

The kvm.sh script uses kvm-find-errors.sh to evaluate whether or not
a build failed. Unfortunately, kvm-find-errors.sh returns success if
there are no failed runs (including when there are no runs at all) even if
there are build failures. This commit therefore makes kvm-find-errors.sh
return failure in response to build failures.

Given that kvm.sh in invoked from scripts, it is only natural for
different levels of scripting to provide their own Kconfig option values,
for example. Unfortunately, right now, the last such argument on the
command line wins.
This commit therefore makes the --bootargs, --configs, --kconfigs,
--kmake-args, and --qemu-args argument values accumulate. For example,
where "--configs TREE01 --configs TREE02" would previously have run only
scenario TREE02, now it will run both scenarios.

Currently, the "date" command producing the output on the kvm.sh "Test
Summary" line is executed at the beginning of the test, which produces a
date that is less than helpful to someone wanting to know the duration
of the test. This commit therefore defers this command's execution to
the end of the test.

The rcutorture scripts' identify_qemu_vcpus() function expects `lscpu`
to have a "CPU: " line, for example:
CPU(s): 8
But different local language settings can give different results:
Processeur(s) : 8
As a result, identify_qemu_vcpus() may return an empty string, resulting
in the following warning (with the same local language settings):
kvm-test-1-run.sh: ligne 138 : test: : nombre entier attendu comme expression
This commit therefore changes identify_qemu_vcpus() to use getconf,
which produces local-language-independend output.

Distributed execution of rcutorture is eased if the qemu execution can
be split from the building of the kernel, as this allows target systems
to be used that are not set up to build kernels. It also avoids issues
with toolchain version skew across the cluster, aside of course from
qemu and KVM version skew.
This commit therefore records needed data as comments in the qemu-cmd file
and moves recording of the starting time to just before qemu is launched.

Scripts like kvm-check-branches.sh group runs under a single directory
in resdir in order to allow easier retrospective analysis. However, they
do this by letting kvm.sh create a directory as usual and then moving it
after the run. This can be very confusing when looking at the results
while kvm-check-branches.sh is running. This commit therefore enables
--datestamp to hand subdirectories to kvm.sh.

A separate field isn't strictly required. The core field could be
re-used for thread IDs as a single field was used previously.
But separating them will avoid confusion and catch potential errors
where core IDs are read as thread IDs and vice versa.
Also remove the placeholder id field which is now no longer used.

Add socket as a separate member so that it doesn't have to be packed
into the int value.
When the socket ID was larger than 8 bits the output appeared corrupted
or incomplete.
For example, here on ThunderX2 'perf stat' reports a socket of -1 and an
invalid die number:
./perf stat -a --per-die
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized
...
S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized
...
And with --per-core there is an entry with an invalid core ID:
./perf stat record -a --per-core
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized
...
S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized
...
This fixes the "Session topology" self test on ThunderX2.
After this fix the output contains the correct socket and die IDs and no
longer prints a warning about the size of the socket ID:
./perf stat --per-die -a
Performance counter stats for 'system wide':
S36-D0 128 169,869.39 msec cpu-clock # 127.501 CPUs utilized

Warning: Kernel ABI header at 'tools/perf/arch/s390/entry/syscalls/syscall.tbl' differs from latest version at 'arch/s390/kernel/syscalls/syscall.tbl'
Just make them same:
cp arch/s390/kernel/syscalls/syscall.tbl tools/perf/arch/s390/entry/syscalls/syscall.tbl

It is better to check syscall.tbl for s390 in check-headers.sh, it is
similar with commit c9b51a017065 ("perf tools: Move syscall_64.tbl check
into check-headers.sh").

That don't causes any changes in tooling, only addresses this perf build
