Subject: [PATCH] fix zx1 config to work on NUMA sx1000 systems
Date: Wed, 04 Aug 2004 16:20:36 +0000 [thread overview]
Message-ID: <1091636436.8451.15.camel@tdi> (raw)
Using CONFIG_IA64_HP_ZX1 on an sx1000 system setup w/ multiple NUMA
nodes (configured for cell local memory) currently crashes because
MAX_NUMNODES defaults to 1. The patch below sets up things to make this
work. Tony, please apply. Thanks,
Alex
