Correct the DSCR SPR becoming temporarily corrupted if a task is context switched during a transaction. The problem occurs while suspending the task and is caused by saving the DSCR to thread.dscr after it has already been set to the CPU's default value: __switch_to() calls __switch_to_tm() which calls tm_reclaim_task() which calls tm_reclaim_thread() which calls tm_reclaim() where the DSCR is set to the CPU's default __switch_to() calls _switch() where thread.dscr is set to the DSCR When the task is resumed, it's transaction will be doomed (as usual) and the DSCR SPR will be corrupted, although the checkpointed value will be correct. Therefore the DSCR will be immediately corrected by the transaction aborting, unless it has been suspended. In that case the incorrect value can be seen by the task until it resumes the transaction. The fix is to treat the DSCR similarly to the TAR and save it early in __switch_to(). A program exposing the problem is added to the kernel self tests as: tools/testing/selftests/powerpc/tm/tm-resched-dscr.

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.

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. Signed-off-by: NPaul E. McKenney <paulmck@linux.vnet.ibm.com>

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.

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.

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.
