Konstantin Belousov 35dfc644f5 Copy the fencing of the algorithm to do lock-less update and reading ... of the timehands, from the kern_tc.c implementation to vdso. Add comments giving hints where to look for the algorithm explanation. To compensate the removal of rmb() in userspace binuptime(), add explicit lfence instruction before rdtsc. On i386, add usual complications to detect SSE2 presence; assume that old CPUs which do not implement SSE2 also execute rdtsc almost in order.
