Subject: [PATCH] enable CONFIG_KALLSYMS_ALL unconditionally after allnoconfig

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.

Normally kallsyms only contains the symbols of functions, for nicer
OOPS messages. Some debuggers can use kallsyms for other

Include in-kernel hooks for the xmon kernel monitor/debugger.
Unless you are intending to debug the kernel, say N here.

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