Subject: [PATCH 0/3] fix alloc_coherent allocation issues (tip/x86/iommu)

This patchset restores some of the current alloc_coherent behaviors
that Joerg's x86 patchset (in tip/x86/iommu) changes.

The first patch uses __GFP_DMA for NULL device argument (fallback_dev)
with pci-nommu. It's a hack for ISA (and some old code) so we need
DMA_ZONE.

The second patch uses __GFP_NORETRY in the case of GFP_DMA.

The third patch is a minor cleanup.

I'll send patchset for the rest of alloc_coherent issues this weekend.
