Christian König dce34bfd63 drm/radeon: refactor set_page chipset interface v5 
Cleanup the interface in preparation for hierarchical page tables.

v2: add incr parameter to set_page for simple scattered PTs uptates
    added PDE-specific flags to r600_flags and radeon_drm.h
    removed superfluous value masking with 0xffffffff

v3: removed superfluous bo_va->valid checking
    changed R600_PTE_VALID to R600_ENTRY_VALID to handle PDE too

v4 (ck): fix indention style, rework and fix typos in commit message,
         add documentation for incr parameter, also use incr
         parameter for system pages

v5 (agd5f): use upper_32_bits() and minor white space fixes

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
    http://dri.freedesktop.org/wiki/Documentation
