No problem.

Against a clean 3.7.10 (from ftp.kernel.org)

# patch -p1 <
../patch/RFC-Fix-Intel-IOMMU-support-for-Marvell-88SE91xx-SATA-controllers..
patch 
patching file drivers/iommu/intel-iommu.c
patching file drivers/pci/quirks.c
Hunk #1 succeeded at 3230 (offset 3 lines).
patching file include/linux/pci.h
# pwd
/usr/src/linux-3.7.10

Full dmesg with the patch applied: (but with IOMMU off)
http://home.comcast.net/~jpiszcz/20130301/dmesg-full.txt

Full dmesg (as much as possible through netconsole with IOMMU on)
http://home.comcast.net/~jpiszcz/20130301/dmesg-iommu-on.txt

Let me know if anything else is needed, thanks.

Justin.
