I believe the seccomp infrastructure (which is already upstream)
should be able to do most of what you want, at least with respect to
features which are exposed via system calls (which was most of your
list).
It won't cover x86 specific things like restricting RDTSC or CPUID
(and as far as I know you can't intercept the CPUID instruction), but
I'm not sure it matters. I don't really see the point, myself.
