[$] Weighted memory interleaving and new system calls

Gregory Price recently posteda patch set that adds support for weighted memory interleaving - allowing aprocess's memory to be distributed betweennon-uniform memory access (NUMA)nodes in a more controlled way.According to his performance measurements, the patch set could provide asignificant improvement for computers with network-attached memory.The patch set alsointroduces new system calls and paves the way for future extensionsintended to give processes more control over their own memory.
