Subject: [PATCH] Fixed the handling of device aliases in the AMD IOMMU driver.
Date: Thu, 14 May 2009 14:08:11 +0100	[thread overview]
Message-ID: <4A0C17BB.4010300@solarflare.com> (raw)

The devid parameter to set_dev_entry_from_acpi is the requester ID
rather than the device ID since it is used to index the IOMMU device
table.  The handling of IVHD_DEV_ALIAS used to pass the device ID.
This patch fixes it to pass the requester ID.
