I have two more very general comments about the series:

a) something has gone wrong with your submission in v2 and v3 but was
   working earlier: normally all emails should be sent by git-send-email
   as replies to the [patch 00/22] mail. This is the default, and it
   is enabled by the '--thread --no-chain-reply' options. Please try
   to get this to work again.

b) it would be better to have a little shorter subject lines, to avoid
   line-wrapping in the list above. Here are some examples what you could
   use to replace the lines above:

   timekeeping: introduce struct itimerspec64
   timekeeping: introduce current_kernel_time64()
   hrtimer: introduce hrtimer_get_res64() 
   posix-timers: split up sys_timer_gettime()
   posix-timers: convert timer_gettime() to timespec64

   In general, try to come up with the shortest description that
   uniquely describes what your patch does, and move any details into
   the longer patch description.
