Subject: [PATCH] arm64: Kconfig: Enable NODES_SPAN_OTHER_NODES config for NUMA
Date: Mon, 3 Feb 2020 11:55:14 -0800 [thread overview]
Message-ID: <1580759714-4614-1-git-send-email-Hoan@os.amperecomputing.com> (raw)
Some NUMA nodes have memory ranges that span other nodes.
Even though a pfn is valid and between a node's start and end pfns,
it may not reside on that node.
This patch enables NODES_SPAN_OTHER_NODES config for NUMA to support
this type of NUMA layout.
