kconfig.debug for 2.6.8

Here's the Kconfig.debug patch updated for 2.6.8:

http://developer.osdl.org/rddunlap/kconfig/kconfig-debug-268.patch

Localize Kconfig debug options into one file (lib/Kconfig.debug) for easier maintenance, searching, and menu-building.

Updated to 2.6.8.

Summary of changes:

. localizes the following symbols in lib/Kconfig.debug:
DEBUG_KERNEL, MAGIC_SYSRQ, DEBUG_SLAB, DEBUG_SPINLOCK, DEBUG_SPINLOCK_SLEEP, DEBUG_HIGHMEM, DEBUG_BUGVERBOSE, DEBUG_INFO
and FRAME_POINTER for some instances of it (if it's freely user-selectable) but not for the cases where it's forced or it depends on some other options.
. adds DEBUG_KERNEL requirement to some DEBUG_vars;
. remove KALLSYMS from S390-specific kernel hacking menu;
use KALLSYMS in the EMBEDDED menu instead;
. add CRIS and M68KNOMMU symbols for use in lib/Kconfig.debug; . eliminate duplicate "General setup" labels in sparc64 config; . whitespace cleanup;
. fixed a few trival typos;

Hi Andrew.

Any good way we can bring this patch forward?
Currently it causes 9 rejects in -mm, and I understand why you are not inclined to fix that up.

I can see clashes with at least LOCKMETER, SCHEDSTATS and KGDB in -mm.

Would it be better to divide it in smaller parts?
o lib/Kconfig.debug
o i386 specific changes
o ia64 specific changes
o architectures that do not cause rejects in -mm + -vanilla
o etc.

The rejects may still be present, but make it easier to pick what applies, and drop the rest for now.

Along the lines of Kconfig.drivers - but hopefully introduced a bit faster.

Sam

Yeah, it's painful. I'd be inclined to base it against -linus and then fix up the individual -mm patches. It's a matter of finding a suitable time
window in which to do that. I'll take a shot at it tomorrow.
