It is enough to keep default values for base and huge pages without
letting users to override ARCH_FORCE_MAX_ORDER.
Drop the prompt to make the option unvisible in *config.

If you're unsure, answer N.
config ARCH_FORCE_MAX_ORDER
- int "MAX_ORDER (10 - 16)" if !HUGETLB_PAGE
- range 10 16 if !HUGETLB_PAGE
+ int
default "16" if HUGETLB_PAGE
default "10"
It seems that we could drop the following part?
ia64 can have 64k pages, so with MAX_ORDER==16 we'd need at least 32 bits
for section size
