Merge tag 'ttm-next-2014-01-13' of git://people.freedesktop.org/~thomash/linux into drm-next
Some code cleanup by Rashika Keria,
VM stuff for ttm:
-Use PFNMAP instead of MIXEDMAP where possible for performance
-Refuse to fault imported pages, an initial step to support dma-bufs
better from within TTM.
-Correctly set page mapping and -index members. These are needed in various
places in the vm subsystem that we are not using yet, but plan to use soonish:
For example unmap-mapping-range keeping COW pages, and dirty tracking
fbdefio style, but also for PCI memory.
