drm: Move vblank related module options into drm_irq.c This allows us to drop 2 header declarations from drmP.h. The 3rd one is also used in drm_ioctl.c, so for that create a new drm_internal.h header for non-legacy non-kms (since we have internal headers for those parts already) declarations private to drm.ko.

drm: Move piles of functions from drmP.h to drm_internal.h This way drivers can't grow crazy ideas any more, and it also helps a bit in reviewing EXPORT_SYMBOLS. v2: Even more stuff. Unfortunately we can't move drm_vm_open_locked because exynos does some horrible stuff with it. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm: unexport drm_global_mutex Drivers really, really have no business even looking at this lock. And thankfully they don't. So unexport it and move the declaration to drm_internal.h. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm: Put legacy lastclose work into drm_legacy_dev_reinit Except for the ->lasclose driver callback evrything in drm_lastclose() is all legacy cruft and can be hidden. Which means another dev->struct_mutex site disappears entirely for modern drivers! Also while at it change the return value of drm_lastclose to void since it will always succeed. No one checks the return value of close() anyway, ever. v2: Move misplaced hunk, spotted by 0day.

drm: Move master functions into drm_auth.c For modern drivers pretty much the only thing drm_master does is handling authentication for the primary/legacy drm_minor node. Instead of having it all over drm files, move it all together into drm_auth.c. This patch just does code-motion, follow up patches will also extract the master logic from file open&release paths.

drm: move drm_class into drm_sysfs.c Right now, drm_sysfs_create() returns the newly allocated "struct class" to the caller (which is drm_core_init()), which then has to set the global variable 'drm_class'. During cleanup, though, we call drm_sysfs_destroy() which implicitly uses the global 'drm_class'. This is confusing, as ownership of the global 'drm_class' is non-obvious. This patch changes drm_sysfs_create() to drm_sysfs_init() and makes it initialize the 'drm_class' object directly, rather than returning it. This way, both drm_sysfs_init() and drm_sysfs_destroy() work in a similar fashion and manage the global drm class.
