1fbfd9eb32 Security and optimization fixes for the via drm: 
1. The command verifier was never initialized in the non-core source tree.
2. Check added that the AGP ring buffer has been initialized before
    accepting command buffer.
3. Free space check in the AGP buffer is moved to after command
    verification, which is more optimal in most cases.

267e064527 Added 3D functionality to the via command verifier. Modified the via 
ring-buffer code somewhat to workaround hardware problems. Bumped via
    minor version number.

4f8fa60286 Reworked PCI MMIO command buffer parser, and imported code from the Mesa 
driver. It can now handle the 3D OpenGL commands from the Mesa
    unichrome driver.
Added vsync frequency detection support. This will be used in the future
    for XvMC and better frame timing.
Bumped minor version number and driver date.

f08a01c0e2 Fixed bug in via_dma.c. The code didn't check that the lock was held by the 
caller. Just that it was held.

9409d8231c Reworked the jump-code in via_dma.c. The command regulator now seems to 
pause correctly after a jump. Removed the debug message from within the
    interrupt handler of via_irq.c

8264e2c8aa Some stabilizing work to the DMA ring-buffer code. Temporarily replaced the 
rewind jump with a reinitialization. This makes the code stable on
    CLE266 and KM400.

bbfe18e3bf Via updates. Fixed unlikely but possible uint32_t overflow in ring-buffer 
code. bumped patchlevel.

dd83f39f03 Add a "dev" argument to DRIVER_CTX_[CD]TOR. This will be used in an 
upcoming commit for the SiS driver.

6f6d2a553a 1. Added a PCI ID. 
2. Big change to the XvMC part of the SAREA. OpenGL clients will not suffer
    from this, and via XvMC is still alpha. Needed to make future additions
    to XvMC (More decoders and overlays) possible.
3. Bumped version number to 1.3.0.
