From dc01c9fae1c5e40458c086a868d2028dfd6faebd Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 16 Jul 2014 21:03:49 +0000 Subject: tile: Convert VDSO timekeeping to the precise mechanism The code was only halfarsed converted to the new VSDO update mechanism and still uses the inaccurate base value which lacks the fractional part of xtime_nsec. Fix it up.
