Hi,
No huge change here, just addressed reviews and fixed warnings:
* Reposted patch 1 separately with appropriate "Fixes:" tag and stable Cc'ed:
https://lore.kernel.org/lkml/20200703010657.2302-1-freder...
* Fix missing initialization of next_expiry in 4/9 (thanks Juri)
* Dropped "timer: Simplify LVL_START() and calc_index()" and added comments
to explain current layout instead in 2/9 (thanks Thomas)
* Rewrote changelog of 9/9 (Thanks Thomas)
