Subject: [PATCH 0/2] IOMMU: use ioremap()
Date: Wed, 10 Jul 2013 11:36:33 +0100	[thread overview]
Message-ID: <51DD555102000078000E3D11@nat28.tlf.novell.com> (raw)

Both AMD IOMMU and VT-d code used iounmap() in their error cleanup
path for something not established via ioremap(), leading to crashes
if those error paths actually get used.

1: VT-d: use ioremap()
2: AMD IOMMU: use ioremap()
