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)
