[PATCH v3 0/1] Add a mach host operation which returns elapsed time since bootup

[Zhaoming Luo]

Compared with v2, an atomic operation is used to avoid data race. About
the idea suggested by Luca, exposing the uptime with a kernel device
that can be memory mapped, I haven't came out with an implementation I'm happy
with. Any suggestion is welcome :).
