x86/iommu/vt-d: Expand interrupt remapping quirk to cover x58 chipset
Recently we added an early quirk to detect 5500/5520 chipsets with early revisions that had problems with irq draining with interrupt remapping enabled: commit 03bbcb2e Author: Neil Horman <nhorman@tuxdriver.com> Date: Tue Apr 16 16:38:32 2013 -0400 iommu/vt-d: add quirk for broken interrupt remapping on 55XX chipsets It turns out this same problem is present in the intel X58 chipset as well. See errata 69 here: http://www.intel.com/content/www/us/en/chipsets/x58-express-specification-update.html This patch extends the pci early quirk so that the chip devices/revisions specified in the above update are also covered in the same way: Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> Reviewed-by: NJan Beulich <jbeulich@suse.com> Acked-by: NDonald Dutile <ddutile@redhat.com> Cc: Joerg Roedel <joro@8bytes.org> Cc: Andrew Cooper <andrew.cooper3@citrix.com> Cc: Malcolm Crossley <malcolm.crossley@citrix.com> Cc: Prarit Bhargava <prarit@redhat.com> Cc: Don Zickus <dzickus@redhat.com> Cc: stable@vger.kernel.org Link: http://lkml.kernel.org/r/1374059639-8631-1-git-send-email-nhorman@tuxdriver.com [ Small edits. ] Signed-off-by: NIngo Molnar <mingo@kernel.org>
