From 05104a4e8713b27291c7bb49c1e7e68b4e243571 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Fri, 27 Sep 2013 12:53:35 -0400 Subject: [PATCH] iommu: Remove stack trace from broken irq remapping warning The warning for the irq remapping broken check in intel_irq_remapping.c is pretty pointless. We need the warning, but we know where its comming from, the stack trace will always be the same, and it needlessly triggers things like Abrt. This changes the warning to just print a text warning about BIOS being broken, without the stack trace, then sets the appropriate taint bit. Since we automatically disable irq remapping, theres no need to contiue making Abrt jump at this problem Signed-off-by: Neil Horman CC: Joerg Roedel CC: Bjorn Helgaas CC: Andy Lutomirski CC: Konrad Rzeszutek Wilk CC: Sebastian Andrzej Siewior Signed-off-by: Joerg Roedel --- drivers/iommu/intel_irq_remapping.c | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) diff --git a/drivers/iommu/intel_irq_remapping.c b/drivers/iommu/intel_irq_remapping.c index f71673dbb23d..b97d70b1abe0 100644 --- a/drivers/iommu/intel_irq_remapping.c +++ b/drivers/iommu/intel_irq_remapping.c @@ -525,12 +525,13 @@ static int __init intel_irq_remapping_supported(void) if (disable_irq_remap) return 0; if (irq_remap_broken) { - WARN_TAINT(1, TAINT_FIRMWARE_WORKAROUND, - "This system BIOS has enabled interrupt remapping\n" - "on a chipset that contains an erratum making that\n" - "feature unstable.
