This and the following two patches will cause interesting conflicts
with two commits in Ben Herrenschmidt's powerpc.git next branch,
specifically 8fd63a9e ("powerpc: Rework VDSO gettimeofday to prevent
time going backwards") and c1aa687d ("powerpc: Clean up obsolete code
relating to decrementer and timebase") from me. In fact the first of
those two commits includes changes equivalent to those in your 5/11
patch ("powerpc: Cleanup xtime usage"), as far as I can see.
