Yeah, maybe a _SHIFT suffix would have been better fit for these configs
instead of _BITS. Similar to PAGE_SHIFT or NODES_SHIFT. Anyways, I can
send a patch to improve the help text. How about something like:
   "Size for ... (as a power of 2)"

I'll also send a separate patch to fix the rest of the upper limits. Any
of the (1 << 30) shifts allocates static arrays that blow past the .bss
segment. Just as originally reporeted by J. R. Okajima.
