The write-up below is the first draft of a proposal for how the kernel can
expose
platform devices to user space using vfio.
In short, I'm proposing a new ioctl VFIO_DEVICE_GET_DEVTREE_INFO which
allows user space to correlate regions and interrupts to the corresponding
device tree node structure

Why ? More junk code to keep around ...

We want to use CMA for allocating hash page table and real mode area for
PPC64. Hence move DMA contiguous related changes into a seperate config
so that ppc64 can enable CMA without requiring DMA contiguous.
