Subject: [PATCH 0/3] x86, AMD: GART optimization

From: Borislav Petkov <borislav.petkov@....com>

Hi,

this is a mini-set that disables the generation of GART TLB walk probes
and should improve GART TLB walk speed when the GART is being used as an
IOMMU. We've been hammering on the changes with a bunch of iotests from
the autotest suite and using "iommu=force" for a while now and have seen
no regressions so far.

Please apply,

Thanks.
