Subject: asm-i386/numaq.h fixes
Date: Sun, 16 Feb 2003 23:51:07 -0800	[thread overview]
Message-ID: <20030217075107.GA14324@holomorphy.com> (raw)

As can be seen from:

http://www-3.ibm.com/software/data/db2/benchmarks/050300.html

MAX_NUMNODES is 16 on NUMA-Q, not 8.

Also, PHYSADDR_TO_NID() needs to parenthesize its argument.
