Subject: [PATCH v7 15/15] acpi, numa: Enable ACPI based NUMA on ARM64
From: Hanjun Guo <hanjun.guo@...aro.org>
Add function needed for cpu to node mapping, and enable ACPI based
NUMA for ARM64 in Kconfig
Signed-off-by: Hanjun Guo <hanjun.guo@...aro.org>
Signed-off-by: Robert Richter <rrichter@...ium.com>
[david.daney@...ium.com added ACPI_NUMA default to y for ARM64]
