Subject[patch] fix wrong uptime on non-i386 platforms
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.
