This changes the fb name from "nouveaufb" to "nouveaudrmfb". Aside: I wonder whether the in_interrupt() check is good enough for the nouveau acceleration. Cargo-cult says drm_can_sleep() is needed, which isn't actually working if you pick a .config without PREEMPT. For the generic fbdev defio support we've gone with offloading everything to a worker. For the non-accel callbacks (set_par, blank and friends) checking for oops_in_progress is good enough to catch all the evil...

DRM client buffers are permanently mapped throughout their lifetime. This prevents us from using generic framebuffer emulation for devices with small dedicated video memory, such as ast or mgag200. With fb buffers permanently mapped, such devices often won't have enougth space left to display other content (e.g., X11). This patch set introduces unmappable DRM client buffers for framebuffer

Several simple framebuffer drivers copy most of the TTM code from each other. The implementation is always the same; except for the name of some data structures. As recently discussed, this patch set provides generic memory-management code for simple framebuffers with dedicated video memory. It further converts the respective drivers to the generic code. The shared code is basically the same
