From d49c4288407b2ffa8cab270cb5bc6882abe969f6 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 8 Jun 2008 18:31:54 -0700 Subject: x86: make generic arch support NUMAQ ... so it could fall back to normal numa and we'd reduce the impact of the NUMAQ subarch. NUMAQ depends on GENERICARCH also decouple genericarch numa from acpi. also make it fall back to bigsmp if apicid > 8.
