This is a note to let you know that I have just added a patch titled x86/amd/numa: Fix northbridge quirk to assign correct NUMA node to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 0ed92f2cfe5928d3ed72c76f154c003629ce8d3b Mon Sep 17 00:00:00 2001 From: Daniel J Blueman <daniel@numascale.com> Date: Thu, 13 Mar 2014 19:43:01 +0800 Subject: x86/amd/numa: Fix northbridge quirk to assign correct NUMA node commit 847d7970defb45540735b3fb4e88471c27cacd85 upstream. For systems with multiple servers and routed fabric, all northbridges get assigned to the first server. Fix this by also using the node reported from the PCI bus. For single-fabric systems, the northbriges are on PCI bus 0 by definition, which are on NUMA node 0 by definition, so this is invarient on most systems. Tested on fam10h and fam15h single and multi-fabric systems and candidate for stable.
