What is the overhead of ktime_get()?
I think I'd like an arch specific timestamp. This way we could use our
clock-cycle-granularity-non-privileged-timestamp instruction ;-). If
we need a common implementation, I don't think there's much difference
between different syscalls in terms of overhead.
This is all in-kernel, so no syscalls. Since I doubt you need sub-ns
granularity for kvmtrace, can we do without an arch hook?
