Help text

Say Y here to produce compact memory node tables. By default pairs of adjacent physical RAM banks are managed together in a single node, incurring some wasted overhead in the node tables, however also maintaining compatibility with systems where physical memory is truly contiguous.

Setting this option incorrectly may prevent the kernel from booting. It is OK to leave it N.
