[PATCH] x86_64: Increase NUMA hash function nodemap

6fa679fd · Andi Kleen <[email protected]> · 2006-04-18 12:35:16 +02:00

Needed for some big Opteron systems to compute a numa hash function
They have more than 12 bits significant address.

TBD switch this over to dynamic allocation or use better hash
