[GIT PULL]: clocksource: new material for 3.13

Hi Thomas,
this pull request is based on 3.12-rc3 with the following content:
- Miroslav improved the RTC update by increasing the interval
acceptable for an update in the sync_cmos_clock workqueue callback
- Prarit added a missing function declaration to fix a compilation
issue on x86. Please *note*, this patch is coming from a pull from
John's tree, it would make sense to cherry-pick this fix into timers/urgent
- Soren added FEAT_PERCPU to a clock device when it is local per cpu.
This feature prevents the clock framework to choose a per cpu timer as a
broadcast timer. This problem arised when the ARM global timer is used
which is the case now on Xillinx.
- Stephen extended the generic sched_clock code to support 64bit
counters and removes the setup_sched_clock deprecation, as that causes
lots of warnings since there's still users in the arch/arm tree.
- Will and Sudeep implemented the event stream for architected timer.
The event streams can be used to impose a timeout on a wfe, to safeguard
against any programming error in case an expected event is not generated
or even to implement wfe-based timeouts for userspace locking
implementations.
- Zoran prevents to enter suspend mode if there are pending RTC timers
to be handled, avoiding these ones to be delayed as well as the
subsequent possible time critical code tied with them.
Thanks
