Hrmpf,

Talk about timing - looks like my NUMA change is not needed given the
two other patches that went in end of last week. So much for spending
3 days chasing this one down :-(

Anyway we still want to set PADDR_BITS to 48 and save about 5KB per
node.

Cheers,
Jes

Set PADDR_BITS to 48 to match reality and save about 5KB per node.
