Dave Airlie 72a1190f6d drm/ttm: make sure dev_mapping is set-up for the first opener of the drm 
This was causing an oops in my miniglx code to try and use a TTM-only setup.

Thomas Hellstrom e1460426b8 Bugzilla Bug #9457 
Add refcounting of user waiters to the DRM hardware lock, so that we can use the
DRM_LOCK_CONT flag more conservatively.

Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context,
when it is released. This is useful when waiting for idle and can be used
for very simple fence object driver implementations for the new memory manager.

It also resolves the AIGLX startup deadlock for the sis and the via drivers.
i810, i830 still require that the hardware lock is really taken so the deadlock remains
for those two. I'm not sure about ffb. Anyone familiar with that code?

Thomas Hellstrom 81251bf78f Reclaim buffers locked fixup. 
Avoid calling reclaim_buffers_locked if we don't have a
hardware lock.

Improve reclaim_buffers_locked deadlock error formatting.

Eric Anholt c789ea1521 Rename the driver hooks in the DRM to something a little more 
understandable: preinit -> load postinit -> (removed) presetup ->
    firstopen postsetup -> (removed) open_helper -> open prerelease ->
    preclose free_filp_priv -> postclose pretakedown -> lastclose
    postcleanup -> unload release -> reclaim_buffers_locked version ->
    (removed)
postinit and version were replaced with generic code in the Linux DRM
    (drivers now set their version numbers and description in the driver
    structure, like on BSD). postsetup wasn't used at all. Fixes the savage
    hooks for initializing and tearing down mappings at the right times.
    Testing involved at least starting X, running glxgears, killing
    glxgears, exiting X, and repeating.
Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)

Michel Daenzer 2655ccddf4 Memory layout transition: 
the 2D driver initializes MC_FB_LOCATION and related registers sanely
the DRM deduces the layout from these registers
clients use the new SETPARAM ioctl to tell the DRM where they think the
    framebuffer is located in the card's address space
the DRM uses all this information to check client state and fix it up if
    necessary
This is a prerequisite for things like direct rendering with IGP chips and
    video capturing.

David Dawes c2d7ff1bf9 Bring some drm module changes over from the XFree86 trunk: 
- Reset 'bound' flag for an agp entry after undbind succeeded in
    drm_agpsupport.h (Egbert Eich).
- Ignore hw_lock for drm device if lock was set by a different instance (ie
    Xserver) to prevent second server from spinning in driver release
    function (currently only relevant for i8xx drm drivers) (David Dawes).
- Use the agpgart "key" for the unique handle for bindings rather than the
    memory address (the key is guaranteed to be unique) (David Dawes).
