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. ttm-next 2013-01-14 pull request * tag 'ttm-next-2014-01-13' of git://people.freedesktop.org/~thomash/linux: drivers: gpu: Remove unused function in ttm_lock.c drivers: gpu: Mark function as static in ttm_bo_util.c drivers: gpu: Mark function as static in ttm_bo.c drm/ttm: Correctly set page mapping and -index members drm/ttm: Refuse to fault (prime-) imported pages drm/ttm: Use VM_PFNMAP for shared bo maps |
