Christoph Lameter 685db65e42 [PATCH] time_interpolator: Use readq_relaxed() instead of readq().
On some platforms readq performs additional work to make sure I/O is done
in a coherent way.  This is not needed for time retrieval as done by the
time interpolator.  So we can use readq_relaxed instead which will improve
performance.

It affects sparc64 and ia64 only.  Apparently it makes a significant
difference on ia64.
