Subject: [PATCH 2/2] Allow any x86 sub-architecture type to set CONFIG_NUMA
Date: Fri, 18 Jan 2008 15:36:09 +0000 (GMT)	[thread overview]
Message-ID: <20080118153609.12646.97784.sendpatchset@skynet.skynet.ie> (raw)
In-Reply-To: <20080118153529.12646.5260.sendpatchset@skynet.skynet.ie>


While there are a limited number of x86 sub-architecture types that can
really support NUMA, there is nothing stopping other machines booting that
type of kernel. The fact that X86_GENERICARCH can set NUMA currently is an
indicator of that. This restriction only limits potential testing coverage.
This patch allows any sub-architecture to set CONFIG_NUMA if they wish.
