Pull timer core updates from Thomas Gleixner:

 - Inline timecounter_cyc2time() as that is now used in the networking
   hotpath. Inlining it significantly improves performance.

 - Optimize the tick dependency check in case that the tracepoint is
   disabled, which improves the hotpath performance in the tick
   management code, which is a hotpath on transitions in and out of
   idle.

 - The usual cleanups and improvements
