Hi Ben,

I can think of two ways to add the new config option.  One would be to
have a large entry in ~/arch/Kconfig, with a default COMMAND_LINE_SIZE
line for each architecture.  The other way would be to have the default
value for COMMAND_LINE_SIZE in the architecture sub-directory Kconfig
file: ~/arch/powerpc/Kconfig for example.

Do you have a preference for either way?
