Subject: [PATCH v3 0/6] Deferrable timers support for hrtimers/timerfd API

Hello.

This is a combo patch set for support defferability in timerfd.
Due implementation of timerfd is based on hrtimers and only on hrtimers,
it was necessary to add such deferrability into hrtimers too.

It brings benefits for user-land application which don't want to break idle state and for
in-kernel users who want to use hrtimer advantages. 

Alexey Perevalov (2):
  tracing/trivial: Add CLOCK_BOOTIME and CLOCK_TAI for human readable
    clockid trace
  tracing/trivial: Add CLOCK_*_DEFERRABLE for tracing clockids

Anton Vorontsov (3):
  kernel/time: Add new helpers to convert ktime to/from jiffies
  timerfd: Factor out timer-type unspecific timerfd_expire()
  timerfd: Add support for deferrable timers

Thomas Gleixner (1):
  hrtimer: Add support for deferrable timer into the hrtimer
