Optimize NUMA Node Tables for Size


Linux Kernel Configuration
└─>LH7A40X Implementations
└─>Optimize NUMA Node Tables for Size
In linux kernel since version 2.6.12  
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.
