For the trees I maintain I have this repository:

git://git.infradead.org/users/dedekind/maintaining.git

where I store various helper scripts. To test your patch-set I used
"l2-mtd-sh_flctl.sh" script, I run it like this:

../aiaiai/concat-mbox-files ~/tmp/bastian* | ./l2-mtd-general.sh

where ../aiaiai is a clone of aiaiai repository:

git://git.infradead.org/users/dedekind/aiaiai.git

and the concat-mbox-files is a helper script which concatenates several
mbox files. The ~/tmp/bastian* are your patches saved as mbox.

Those helper scripts require you to clone the l2-mtd.git tree and
checkout the "defconfigs" branch which contains the
'l2_makerel_defconfig' configuration.

Aiaiai also needs several packages to be installed - see README file in
the aiaiai repo. It also needs smatch and sparse - also documented in
README. Sorry that this stuff is not too user-friendly - I do not have
time to clean it up.

Feel free to ask for help.
