FREEMAIL_ENVRCPT(0.00)[gmail.com] Move drm_draw.o from the DRM core to drm_pixel_helper.ko. Remove the Kconfig option DRM_DRAW and provide the draw helpers unconditionally. Having draw code in the DRM core is a left-over fro when panic handling was entirely located in the DRM core as well. With all the panic drawing in drm_pixel_helper.ko, the drawing helpers can go there as well. DRM's log clients also uses the drawing helpers for output. Update the Kconfig rules to select DRM_PIXEL_HELPER instead of DRM_DRAW for this client. The format and the draw helpers share the per-pixel color-format code from drm_format_internal. Putting it all into one place will hopefully help with sharing more code in the future.
