Merge tag 'for-linus-timers-conversion-final-v4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux into timers/urgent

Pull the last batch of manual timer conversions from Kees Cook:

 - final batch of "non trivial" timer conversions (multi-tree dependencies,
   things Coccinelle couldn't handle, etc).

 - treewide conversions via Coccinelle, in 4 steps:
   - DEFINE_TIMER() functions converted to struct timer_list * argument
   - init_timer() -> setup_timer()
   - setup_timer() -> timer_setup()
   - setup_timer() -> timer_setup() (with a single embedded structure)

 - deprecated timer API removals (init_timer(), setup_*timer())

 - finalization of new API (remove global casts)
