His latest KVM patch set has that.
Cheers,

The hook dma_get_required_mask is supposed to return the mask required
by the platform to operate efficently. The generic version of
dma_get_required_mask in driver/base/platform.c returns a mask based
only on max_pfn. However, this is likely too big for iommu systems
and co

The new get_required_mask hook name is longer than many of but not all
of the prior ops. Tidy the struct initializers to align the equal signs
using the local whitespace.

If an architecture sets ARCH_HAS_DMA_GET_REQUIRED_MASK and has settable
dma_map_ops, the required mask may change by the ops implementation.
For example, a system that always has an mmu inline may only require 32
bits while a swiotlb would desire bits to cover all of memory.
From: Milton Miller
Now that the generic code has dma_map_ops set, instead of having a
messy ifdef & if block in the base dma_get_required_mask hook push
the computation into the dma ops.
If the ops fails to set the get_required_mask hook default to the
width of dma_addr_t.
This also corrects i
In my last submission, 5/8 wasn't sent to Ben, so he only picked up 1-4.
Re-sending 5-8, as such.

powerpc: override dma_get_required_mask by platform hook and ops
dma-mapping: add get_required_mask if arch overrides default
