Commit c46173183657 ("MIPS: Add NUMA support for Loongson-3") has increased
.bss size of the Octeon kernel from 16k to 16M. Providing the conditions
for SPARSEMEM_EXTREME avoids the waste of memory.
Thomas has tested the loogsoon64 kernel, where .bss is being reduced by
this patch from 16.5M to 515k.

thank for the change, applied to mips-fixes.
Thomas.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
