From 29dcbc5c25d6d8140337e96bf503c8475092c586 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Thu, 2 Dec 2010 16:14:27 -0800 Subject: [PATCH] xen: allocate irq descs on any NUMA node Allocate irq descs on any NUMA node (we don't care) rather than specifically node 0, which may not exist. (At the moment NUMA is meaningless within a domain, so any info the kernel has is just from an SRAT table we haven't suppressed/disabled.)
