From: "Yong, Jonathan" <jonathan.yong at intel.com>

This series introduces convert_art_to_tsc, to convert ART time
to TSC. The main advantage of ART is that ART can be captured
simultaneous to the capture of audio and network device clocks,
allowing a correlation between timebases to be constructed.

The getnstime_raw_and_real symbol has been renamed to
ktime_get_raw_and_real_ts64, including in all consumers.

All patches are already in Linus's kernel.
Patches should apply for linux-yocto-4.1 standard/base.

Arnd Bergmann (1):
  ntp/pps: replace getnstime_raw_and_real with 64-bit version

Christopher S. Hall (4):
  time: Add cycles to nanoseconds translation
  time: Add timekeeping snapshot code capturing system time and counter
  time: Add driver cross timestamp interface for higher precision time
  x86/tsc: Always Running Timer (ART) correlated clocksource

DengChao (1):
  timekeeping: Provide internal function __ktime_get_real_seconds
