2013-04-04ntp: Rework do_adjtimex to take timespec and tai argumentsJohn Stultz
In order to change the locking rules, we need to provide the timespec and tai values rather then having the ntp logic acquire these values itself.

2013-04-04ntp: Move timex validation to timekeeping do_adjtimex call.John Stultz

2013-04-04ntp: Move do_adjtimex() and hardpps() functions to timekeeping.cJohn Stultz
In preparation for changing the ntp locking rules, move do_adjtimex and hardpps accessor functions to timekeeping.c, but keep the code logic in ntp.c. This patch also introduces a ntp_internal.h file so timekeeping specific interfaces of ntp.c can be more limitedly shared with timekeeping.c.
