4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Baoquan He <bhe@xxxxxxxxxx> commit 9b1a12d29109234d2b9718d04d4d404b7da4e794 upstream. In below commit alias DTE is set when its peripheral is setting DTE. However there's a code bug here to wrongly set the alias DTE, correct it in this patch. commit e25bfb56ea7f046b71414e02f80f620deb5c6362 Author: Joerg Roedel <jroedel@xxxxxxx> Date: Tue Oct 20 17:33:38 2015 +0200 iommu/amd: Set alias DTE in do_attach/do_detach Signed-off-by: Baoquan He <bhe@xxxxxxxxxx> Tested-by: Mark Hounschell <markh@xxxxxxxxxx> Signed-off-by: Joerg Roedel <jroedel@xxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/iommu/amd_iommu.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/iommu/amd_iommu.c +++ b/drivers/iommu/amd_iommu.c @@ -1905,7 +1905,7 @@ static void do_attach(struct iommu_dev_d /* Update device table */ set_dte_entry(dev_data->devid, domain, ats); if (alias != dev_data->devid) - set_dte_entry(dev_data->devid, domain, ats); + set_dte_entry(alias, domain, ats); device_flush_dte(dev_data); } -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
