With dma compliance / IOMMU support added to the driver in kernel 3.13,
the dma addresses can exceed 44 bits, which is what we support in
32-bit mode and with GMR1.
So in 32-bit mode and optionally in 64-bit mode, restrict the dma
addresses to 44 bits, and strip the old GMR1 code.

Fixes
*) an implicit function declaration on mips,
*) a defined but not used label on !CONFIG_INTEL_IOMMU
*) Hopefully a couple of sparse warnings where we implicitly typecast
integer to __le32 and vice versa.

The code handles three different cases:
1) physical page addresses. The ttm page array is used.
2) DMA subsystem addresses. A scatter-gather list is used.
3) Coherent pages. The ttm dma pool is used, together with the dma_ttm
array os dma_addr_t

This fixes the piglit test texturing/max-texture-size
causing the VM to die due to a too large SVGA command.

Guest Memory Regions 2 is a way to bind pages to the GPU, but using
the FIFO instead of an io-submitted descriptor chain.

Use Ben's new range manager hooks to implement a manager for
GMRs that manages ids rather than ranges.
This means we can use the standard TTM code for binding, unbinding and
eviction.

This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA.
The driver is under staging the same as Nouveau and Radeon KMS. Hopefully
the 2D ioctls are bug free and don't need changing, so that part of the
API should be stable. But there there is a pretty big chance that the 3D API
will change in the future.
