Please don't do it this way.
In mm/Kconfig, put
default 1234 if POWERPC
The way you have it now, every single architecture that needs to enable
this has to go put that in their Kconfig. That's madness. This way,
you only put it in one place, and folks only have to care if they want
to change the default to be something other than 4.
