Subject: [PATCH v3 0/7] Isolate time_t data types for clock/timer syscalls

The series aims at isolating data conversions of time_t based structures:
struct timespec and struct itimerspec at user space boundaries.
This helps to later change the underlying types to handle y2038 changes
to these.

The series is an update to Arnd Bergmann's previous series:
http://sourceware.org/ml/libc-alpha/2015-05/msg00070.html

Changes since v1:
* Rebased and removed common code paths on the tip linux-next.
Changes since v2:
* Removed accidental inclusion of wrong version of patch 3/7.

Deepa Dinamani (7):
  time: add get_timespec64 and put_timespec64
  time: introduce {get,put}_itimerspec64
  posix-stubs: Conditionally include COMPAT_SYS_NI defines
  posix-timers: Use get_timepsec64() and put_timespec64()
  nanosleep: Use get_timepsec64() and put_timespec64()
  timerfd: Use get_itimerspec64() and put_itimerspec64()
  posix_clocks: Use get_itimerspec64() and  put_itimerspec64()
