Here are most of the missing wall_to_monotonic initializations that the
non-i386 architectures still need to pick up.
This should fix the reported uptime inconsistencies.
Disclaimer: completely untested, since I don't have (most of) the hardware.

This one should normalize wall_to_monotonic so that nsec >= 0 and <
NSEC_PER_SEC.

Incidently, I haven't had the absurdly high uptime bug strike again since
the first time it happened. I'll try out your patch as soon as I get a
chance.

Valid point. Shouldn't i386 (that I blindly copied) also normalize, then?
This time I also added the missing bits to do_settimeofday() for
architectures that don't yet know about wall_to_monotonic.

Uh, I think I missed the initial set up. If tv_nsec is not changed it

Looks like you missed the normalize on the s390 initial set up.
Otherwise it looks good.
