connector->base.id,
drm_get_connector_name(connector),
connector->encoder->base.id,

drm_get_connector_name()) before ending up in drm_ut_debug_printk() which will
then does nothing.
This means we execute a lot of instructions (drm_get_connector_name(), in turn,
calls snprintf() for example) to happily discard them in the normal case,
drm.debug=0.
So, let's put the test on drm_debug earlier, in the macros themselves.

This does *not* (and is not intended to) fix the issue reported by

The patch proposed (which is similar to this one, but also reorders
whether we disable accel or call fb_set_suspend first), papers over
another problem entirely by avoiding touching the framebuffer.

support for platform devices
Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead
of PCI to which Nouveau is tightly dependent. This patch allows Nouveau
to handle platform devices by:
- abstracting PCI-dependent functions that were typically used for
resource querying and page mapping,
- introducing a nv_device_is_pci() function that allows to make
PCI-dependent code conditional,
- providing a nouveau_drm_platform_probe() function that takes a GPU
platform device to be probed.
Core code as well as engine/subdev drivers are updated wherever possible
to make use of these functions. Some older drivers are too dependent on
PCI to be properly updated, but all newer code on which future chips may
depend should at least be runnable with platform devices.
