Patch from Bart Van Assche <bart.vanassche@gmail.com>:

The patch below contains a script that removes C preprocessor tests on the
LINUX_VERSION_CODE macro, depending on the kernel version that was passed as
an argument to that script. Furthermore, the generate-kernel-patch script has
been modified such that its output is filtered by the specialize-patch script.
This eliminates another class of checkpatch errors.

Note: due to the way the specialize-patch script is implemented, #if 0 and
#if 1 statements are also processed.

The patch below has been verified as follows:
- Checked that checkpatch does no longer complain about LINUX_VERSION_CODE
  on the generated patch.
- Checked that the generated kernel patch applies cleanly to the 2.6.25.4
  kernel.
- Checked that the patched kernel compiles and installs cleanly, and that
  after reboot it was possible to load the iscsi-scst and ib_srpt kernel modules.

I will wait with sending more patches until this and the previous two patches
have been reviewed and/or applied.
