I applied the three patches against 2.6.30-git14. We look forward to seeing the changes integrated. On this 2-socket Intel 5500 based system (Nehalem), the /sys stuff looks good: $ ls /sys/devices/system/node/node? /sys/devices/system/node/node0: cpu0 cpu2 cpulist distance numastat cpu1 cpu3 cpumap meminfo scan_unevictable_pages /sys/devices/system/node/node1: cpu4 cpu6 cpulist distance numastat cpu5 cpu7 cpumap meminfo scan_unevictable_pages Where as, before, it looked like this (non-ordered, all CPUs showing up in node 0). # ls -ld /sys/devices/system/node/node* drwxr-xr-x 2 root root 0 2009-06-18 09:30 /sys/devices/system/node/node0 drwxr-xr-x 2 root root 0 2009-06-18 09:30
