Hi -
I submitted a new stripped-down to bare essentials version of
the patch, (see LKML emails with $subject) which passes all
checkpatch.pl tests and addresses all concerns raised by reviewers,
which uses only rdtsc_ordered(), and which only only updates in
vsyscall_gtod_data the new fields:

Resent to address reviewer comments, and allow builds with compilers
that support -DRETPOLINE to succeed.
Currently, the VDSO does not handle
clock_gettime( CLOCK_MONOTONIC_RAW, )
on Intel / AMD - it calls
vdso_fallback_gettime()
for this clock, which issues a syscall,
