The script scripts/specialize-patch'>scripts/specialize-patch is an awk script. Currently it specifies /usr/bin/awk as its interpreter although it doesn't use the standard AWK syntax but the extended GNU AWK syntax. The patch below changes the interpreter name such that the script also works on systems where /usr/bin/awk is not GNU AWK (e.g. Ubuntu 8.04). Note: GNU AWK is not installed by default on all Linux systems. E.g. on Debian systems it's in the gawk package.

The current version of generate-kernel-patch does not remove preprocessor
statements that should have been removed because intended for another kernel
version (surrounded by #if LINUX_VERSION_CODE ... KERNEL_VERSION(...) / #endif).
The patch below fixes this.
I have verified the patch below by comparing the patch generated by the
old and the new versions of the generate-kernel-patch script:

The patch below implements the following changes:
- Make sure the output of the make command does not appear in the generated
kernel patch.
- Changed interpreter of scripts/specialize-patch from /usr/bin/gawk to
/usr/bin/awk in order to make sure this awk script also runs on systems
where awk is installed but not gawk.
- Added an extra evaluation rule such that expressions like (0) are rewritten
as 0.
- Fixed a spelling error.
- Expressions that can only be partially evaluated are now partially evaluated.
E.g. #if defined(EXTRACHECKS) && (LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 18))
becomes #if defined(EXTRACHECKS) && 0 in the output.
- Code between #if 0 / #endif or #if 1 / #endif is included in the generated
kernel patch, including the surrounding preprocessor directives.
- Preprocessor statements with spaces behind # are now recognized (e.g. "# if").
- Expression evaluator now supports ! (logical not) and () (braces).
- #elif is now evaluated correctly.
- Nested #if / #elif / #else / #endif are now interpreted correctly.

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.
