  "message": "powerpc: Improve resolution of VDSO clock_gettime\n\nCurrently the clock_gettime implementation in the VDSO produces a\nresult with microsecond resolution for the cases that are handled\nwithout a system call, i.e. CLOCK_REALTIME and CLOCK_MONOTONIC.  The\nnanoseconds field of the result is obtained by computing a\nmicroseconds value and multiplying by 1000.\n\nThis changes the code in the VDSO to do the computation for\nclock_gettime with nanosecond resolution.  That means that the\nresolution of the result will ultimately depend on the timebase\nfrequency.\n\nBecause the timestamp in the VDSO datapage (stamp_xsec, the real time\ncorresponding to the timebase count in tb_orig_stamp) is in units of\n2^-20 seconds, it doesn\u0027t have sufficient resolution for computing a\nresult with nanosecond resolution.  Therefore this adds a copy of\nxtime to the VDSO datapage and updates it in update_gtod() along with\nthe other time-related fields.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
