+Subject: intel: Change context create failure message to from fprintf to DBG().
+
+Since there is no getparam for hardware context support, Mesa always
+tries to obtain a context by calling drm_intel_gem_context_create and
+NULL-checking the result.  On an older kernel without context support,
+this caused libdrm to print an unwanted message to stderr:
+
+DRM_IOCTL_I915_GEM_CONTEXT_CREATE failed: Invalid argument
+
+In fact, this caused every Piglit test to fail with a "warn" status due
+to the unrecognized error message.
+
+Change the message to use DBG() rather than fprintf(), so people can
+still get the debug message, but it won't spam normally.
