[PATCH 0/2] x86: gart: fix the HW IOMMU initialization rewrite breakage

[FUJITA Tomonori]

Here is the output of discussion with Yinghai Lu. This patchset fixes
GART isses due to the commit 75f1cdf1dda92cae037ec848ae63690d91913eac
(x86: Handle HW IOMMU initialization failure gracefully).

I split Yinghai's v4 patch to make the changes clearer (and fixed the
comment a bit) however there is no functional change:

The first patch is a sligtly modified version of my patch to move back
swiotlb initialization after IOMMU detection:

I put the detailed descriptions to both.
