Pull timekeeping updates from Thomas Gleixner:
"Updates for NTP/timekeeping and PTP:
- Expand timekeeping snapshot mechanisms
The various snapshot functions are mostly used for PTP to collect
"atomic" snapshots of various involved clocks.
They lack support for the recently introduced AUX clocks and do not
provide the underlying counter value (e.g. TSC) to user space.
Exposing the counter value snapshot allows for better control and
steering.
Convert the hard wired ktime_get_snapshot() to take a clock ID,
which allows the caller to select the clock ID to be captured along
with CLOCK_MONONOTONIC_RAW. Additionally capture the underlying
hardware counter value and the clock source ID of the counter.
