It doesn't really have to be that fancy, but I suspect we'll end up
with something along that line. Kconfig doesn't support arithmetik,

config PAGE_SIZE
default 1 << PAGE_SHIFT

doesn't work, requiring the complex defaults.


depends on !PAGE_SIZE || PAGE_SIZE < xxx

doesn't work either, making something like HAVE_PAGE_SIZE mandatory
unless PAGE_SIZE is made available for all architectures, which seems

Of course,
depends on !PPC
would be the simple solution.
