There is nothing that prevents us from using lower maximum values.
It's something that we actually want, when using bigger page sizes

devices with low RAM.

Do we need the range at all ? Most other archs don't use a range...
The maximum contiguous block size cannot be lower than a huge page, so
that's why the 'range' are here.
Which makes me think that there should probably be a "range 11 64 if
MIPS_HUGE_TLB_SUPPORT && PAGE_SIZE_8KB" and the same for 4KB pages.
With a lower value and huge pages enabled in the config, the kernel
probably would not boot.
Cheers,
