The patch below implements the following modifications for

Browse Source 
scripts/run-regression-tests:
- Adds a description about what the script does.
- Added command-line option -c which allows to specify which directory to use
  as cache for kernel tar balls and patch files.
- More error checking.
- scst_local is now included in all the tests.
- Swapped the order of two test steps, namely compiling the whole tree and
  running sparse. This way the output of the sparse tool is available a lot
  sooner.

# This script performs the following actions:
# - Creates a temporary directory for storing the output of the regression
# tests. No existing files are modified by this script.
# - Verifies whether the top-level *.patch files apply cleanly to the SCST
# tree.
# - Duplicates the entire source tree to the temporary directory and
# compiles the SCST source code.
# - Duplicates the entire source tree to the temporary directory, applies
# the full-perf patches and again compiles the SCST source code.
# - Checks whether the kernel version specified through option -k is present
# in the directory specified through option -c.
# - If the source code of the kernel specified through -k is not present,
# download it.
# - Convert the SCST source code into a kernel patch.
# - Extract the kernel sources.
# - Run checkpatch on the SCST kernel patch.
# - Apply the SCST kernel patch to the kernel tree.
# - Run 'make allmodconfig'.
# - Run the sparse source code checker on the SCST directory.
# - Compile the kernel tree.
#
# Note: the results of the individual steps are not verified by this script
# -- the output generated by the individual steps has to be verified by
# reviewing the output files written into the temporary directory.
