Subject: torture: Remove obsolete builddir options

The --builddir and --relbuilddir options were initially intended to handle
parallel tests.  However, since commit 43e38ab3d518 (Enable concurrent
rcutorture runs), the script manages multiple build directories as
needed for parallel testing.  This commit therefore removes these two
obsolete options.

Subject: torture: Make parse-rcutorture.sh less RCU-specific

It can be a bit jarring to see a locking test complain about RCU, so
this commit renames parse-rcutorture.sh to parse-torture.sh and makes
the messages it emits more generic.

Subject: torture: Allow variations of "defconfig" to be specified

Some environments require some variation on "make defconfig" to initialize
the .config file.  This commit therefore adds a --defconfig argument to
allow this to be specified.  The default value is of course "defconfig".

Subject: torture: Make config-fragment filtering RCU-independent

The torture tests need to set specific values for their respective
Kconfig options (e.g., CONFIG_LOCK_TORTURE_TEST), and must therefore
filter any conflicting definitions from the Kconfig fragment
file.  Unfortunately, the code in kvm-build.sh was looking only for
CONFIG_RCU_TORTURE_TEST.  This commit therefore handles the general case
of CONFIG_[A-Z]*_TORTURE_TEST.

Subject: torture: Make "--dryrun script" output self-sufficient

The scripts produced by kvm.sh's "--dryrun script" argument were intended
for debugging rather than to run, but it is easier to debug if the script
output matches exactly what is run.  This commit therefore makes this
script runnable.

Subject: torture: Make "--dryrun script" use same environment as normal run

In a normal torture-test run, the script inherits its environment
variables, but this does not work when producing a script that is
to run later.  Therefore, definitions and exports are prepended to
a dryrun script but not to a script that is run immediately.  This
commit reconciles this by placing definitions and exports at the
beginning of the script in both cases.

Subject: torture: Report diagnostics from qemu

The current script does record qemu diagnostics, but the user has to
know where to look for them.  This commit therefore puts them into the
Warnings file so that kvm-recheck.sh will display them.  This change is
especially useful if you are in the habit of killing the qemu process
when you realize that you messed something up, but then later on wonder
why the process terminated early.

Subject: torture: Choose bzImage location based on architecture

Currently, the scripts hard-code arch/x86/boot/bzImage, which does not
work well for other architectures.  This commit therefore provides a
identify_boot_image function that selects the correct bzImage location
relative to the top of the Linux source tree.  This commit also adds a
--bootimage argument that allows selecting some other file, for example,
"vmlinux".

This change requires that the definition of the QEMU variable be
computed earlier in order to identify where to look for the boot image
when it comes time to copy it to the results directory.

Subject: torture: Better summary diagnostics for build failures

The reaction of kvm-recheck.sh is obscure at best, and easy to miss
completely.  This commit therefore prints "BUG: Build failed" in the
summary at the end of a run.  This commit also adds the line of dashes
in cases where performance info is not available, and also avoids
printing nonsense diagnostics in cases where some of the normal test
output is not available.  In addition, this commit saves off the .config
file even when the build fails.

Subject: torture: Use elapsed time to detect hangs

The kvm-test-1-run.sh currently counts "sleep 1" commands to detect
hangs.  This can fail spectacularly on busy systems, where "sleep 1"
might take far longer than one second to complete.  This commit
therefore changes hang detection to use elapsed time measurements.

TREE_PREEMPT_RCU kernels, a combination that was previously omitted.

Subject: rcutorture: Note diffs from git commits

The current scripting only keeps track of the git SHA-1 of the current
HEAD.  This can cause confusion in cases where testing ran in a git
tree where changes had not yet been checked in.  This commit therefore
also records the output of "git diff HEAD" to provide the information
needed to reconstruct the source tree that was tested.
