Mika Kuoppala b6359918b8 drm/i915: add i915_get_reset_stats_ioctl
This ioctl returns reset stats for specified context.

The struct returned contains context loss counters.

reset_count:    all resets across all contexts
batch_active:   active batches lost on resets
batch_pending:  pending batches lost on resets

v2: get rid of state tracking completely and deliver only counts. Idea
    from Chris Wilson.

v3: fix commit message

v4: default context handled inside i915_gem_context_get_hang_stats

v5: reset_count only for priviledged process

v6: ctx=0 needs CAP_SYS_ADMIN for batch_* counters (Chris Wilson)

v7: context hang stats never returns NULL

v8: rebased on top of reworked context hang stats
    DRM_RENDER_ALLOW for ioctl

v9: use DEFAULT_CONTEXT_ID. Improve comments for ioctl struct members

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

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
