Trying to do anything with kms drivers when oopsing has become a failing proposition. But since we can end up in the fbdev code simply due to the console unblanking that's done unconditionally just removing our panic handler isn't enough. We need to block all fbdev callbacks when oopsing. There was already one in the blank handler, but it failed silently. That makes it impossible for drivers (like i915) who subclass these functions to figure this out. Instead consistently return -EBUSY so that everyone knows that we really don't want to be bothered right now. This also allows us to remove a pile of FIXMEs from the i915 fbdev code (since due to the failure code they now won't attempt to grab dangerous locks any more).

Every drm driver calls framebuffer_alloc, fb_alloc_cmap, unregister_framebuffer, fb_dealloc_cmap and framebuffer_release in order to emulate fbdev support. Create drm_fb_helper functions that perform the above operations. This is part of an effort to prevent drm drivers from calling fbdev functions directly. It also removes repetitive code from drivers. There are some drivers that call alloc_apertures after framebuffer_alloc and some that don't. Make the helper always call alloc_apertures. This would make certain drivers allocate memory for apertures but not use them. Since it's a small amount of memory, it shouldn't be an issue. v2: - Added kerneldocs - Added a check for non-NULL fb_helper before proceeding.

This is required to properly handle failing dpms calls. When making a wait in i915 interruptible, I've noticed that the dpms sequence could fail with -ERESTARTSYS because it was waiting interruptibly for flips. So from now on allow drivers to fail in their connector dpms callback. Encoder and crtc dpms callbacks are unaffected. Changes since v1: - Update kerneldoc for the drm helper functions.

Two nice things here: - drm_dev_register will truly register everything in the right order if the driver doesn't have a ->load callback. Before this we had to init the primary mode_group after the device nodes where already registered. - Less things to keep track of when reworking the connector locking, yay!

It's been dead code since forever since mode groups haven't ever been implemented. On top of that it's also been non-functional since we only ever filtered the getresources ioctl and not any of the others nor the mode object lookup code.

Now that we also grab the connection_mutex and so fixed the race with atomic modeset we can use the iterator there too. The other special case is drm_connector_unplug_all which would have a locking inversion with the sysfs store/show functions if we'd grab the mode_config.mutex around the unplug. We could just grab connection_mutex instead, but that's a bit too much a dirty trick for my taste. Also it's only used by udl, which doesn't do any other kind of connector hotplugging, so should be race-free. Hence just stick with a comment for now.
