There's another bug in there... You fix timespec vs. timespec64 for the
first argument of update_vsyscall_old but not the second one ...
(wall_to_monotonic).

Also, in e2dff1ec0 you claim this is "minor", you seem to forget that
arch/powerpc also deals with 32-bit kernels which use the same time
keeping code, so we have a pretty serious regressions here...

BTW. Is there some documentation you can point me to to figure out what
replace that "_OLD" stuff so we can update to whatever is "new" ?

Cheers,
Ben.
