From 4323838215184f5a2f081e0d17b8d60731b03164 Mon Sep 17 00:00:00 2001 From: "travis@sgi.com" Date: Wed, 30 Jan 2008 13:33:25 +0100 Subject: x86: change size of node ids from u8 to s16 Change the size of node ids for X86_64 from u8 to s16 to accomodate more than 32k nodes and allow for NUMA_NO_NODE (-1) to be sign extended to int.
