clockevent_device::next_event holds the next timer event of a clock event
device. The value is updated in clockevents_program_event(), i.e. when the
hardware timer is armed for the next expiry.

When there are no software timers armed on a CPU, the corresponding per CPU
clockevent device is brought into ONESHOT_STOPPED state, but
clockevent_device::next_event is not updated, because
clockevents_program_event() is not called.

So the content of clockevent_device::next_event is stale, which is not an
issue when real hardware is used. But the hrtimer broadcast device relies
on that information and the stale value causes spurious wakeups.

Update clockevent_device::next_event to KTIME_MAX when it has been brought
into ONESHOT_STOPPED state to avoid spurious wakeups. This reflects the
proper expiry time of the stopped timer: infinity.

Merge branch 'fortglx/4.15/time' of https://git.linaro.org/people/john.stultz/linux into timers/core

Pull timekeeping updates from John Stultz:

 - More y2038 work from Arnd Bergmann

 - A new mechanism to allow RTC drivers to specify the resolution of the
   RTC so the suspend/resume code can make informed decisions whether to
   inject the suspended time or not in case of fast suspend/resume cycles.

The interfaces based on 'struct timespec' and 'unsigned long' seconds
are no longer recommended for new code, and we are trying to migrate to
ktime_t based interfaces and other y2038-safe variants.

This moves all the legacy interfaces from linux/timekeeping.h into a
new timekeeping32.h to better document this.

On 64-bit architectures, the timespec64 based helpers in linux/time.h
are defined as macros pointing to their timespec based counterparts.
This made sense when they were first introduced, but as we are migrating
away from timespec in general, it's much less intuitive now.

This changes the macros to work in the exact opposite way: we always
provide the timespec64 based helpers and define the old interfaces as
macros for them. Now we can move those macros into linux/time32.h, which
already contains the respective helpers for 32-bit architectures.
