=?utf-8?q?Michel_D=C3=A4nzer?= 541f29aad7 drm: DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead 
of pipe number.

Handle relative as well as absolute target sequence numbers.

Return error if target sequence has already passed, so userspace can deal with
this situation as it sees fit.

On success, return the sequence number of the vertical blank when the buffer
swap is expected to take place.

Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want
to use ioctl() instead of drmCommandWriteRead().

************************************************************

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://precisioninsight.com/piinsights.html
