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-frederic@kernel.org/

* 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)
