Author: andrew Date: Fri Aug 4 10:33:22 2017 New Revision: 322051 URL: https://svnweb.freebsd.org/changeset/base/322051 Log: Read the numa-node-id property from each CPU node. This will initially be used to support the dual package ThunderX where we need to send MSI/MSI-X interrupts to the same package as the device the interrupt came from.
