[PATCH 1/2] powerpc/configs: merge pseries_defconfig and pseries_le_defconfig

[PATCH 1/2] powerpc/configs: merge pseries_defconfig and pseries_le_defconfig

[Cyril Bur]

These two configs should be identical with the exception of big or little
endian

The big endian version has XMON_DEFAULT turned on while the little endian has
XMON_DEFAULT not set. Enable XMON_DEFAULT for little endian.

[PATCH 2/2] powerpc: replace pseries_le_defconfig with a Makefile target using merge_config

[Cyril Bur]

Rather than continuing to maintain a copy of pseries_defconfig with enabled
CONFIG_CPU_LITTLE_ENDIAN, use the generic merge_config script and use an
le.config to enable little endian on top of pseries_defconfig without the need
for a duplicated _defconfig file.

This method will require less maintenance in the future and will ensure that
both 'defconfigs' are always in sync.

I disabled it on the LE defconfig on purpose. In most cases we want to
get the kernel back around and running again. I got sick of building a
mainline kernel for a non development box and coming back to it stuck in
xmon.

Should we disable it by default and require developers who want xmon to
set the config option, or use the xmon=on boot?

I think that it's a good idea to keep it disabled by default

Sure, that behaviour makes sense since and the goal here is to have them
be the same, I'll resent the patch to go the other way and turn
XMON_DEFAULT off in big endian.
