Hi Andi,

I'm using CONFIG_DEBUG_INFO, but I used a different mechanism to
select it when KGDB is selected. I'm still learning to speak Kconfig.

My patch:

config KGDB
bool "Include kgdb kernel debugger"
depends on DEBUG_KERNEL
select DEBUG_INFO
help
If you say Y here, the system will be compiled with the debug

Your patch:

config DEBUG_INFO
bool "Compile kernel with debug information" if !KGDB
default y

Using "select DEBUG_INFO" selects the option and makes the input box
on xconfig disappear. The line describing the option remains, perhaps
leaving a user wondering why this line doesn't have an input box.

With your version, the DEBUG_INFO option disappears when KGDB forces
it on.

I was looking for a way to get the old behavior where the
the effect was controlled by an OR of the two options.
