[PATCH] enable CONFIG_KALLSYMS_ALL unconditionally after allnoconfig

[PATCH] enable CONFIG_KALLSYMS_ALL unconditionally after allnoconfig

[Olaf Hering]

CONFIG_KALLSYMS_ALL is disabled after these commands:

rm -rf ../foo-$$
mkdir ../foo-$$
make -j ARCH=powerpc O=../foo-$$ allnoconfig  > /dev/null 
grep KALLSYMS ../foo-$$/.config
make -j ARCH=powerpc O=../foo-$$ menuconfig
 # 'Kernel hacking  ---> ' , enable 'Kernel debugging '
grep KALLSYMS ../foo-$$/.config

enabled it along with CONFIG_KALLSYMS, because CONFIG_KALLSYMS is not selectable per default
xmon can not lookup all symbols without CONFIG_KALLSYMS_ALL,
'ls log_buf' will not work as example.

Unless xmon is completely unusable without CONFIG_KALLSYMS_ALL, I'd rather 
leave it optional.
