Thanks. I did some (make installcheck) tests against it:

Compared with an earlier non-vta compiled kernel:

The two regressions are:

Compared to a systemtap 1.0 testrun (on the vta-enabled-build kernel):

Which shows some more failures for issues apparently solved in recent
systemtap git. It also shows the tval-opt.stp regression, but not the
32_BIT_UTRACE_SYSCALL_ARGS for some reason. So we might want to track
down those two regressions and then try to spin a new release if this
vta-enabled-build kernel hits distros soon.
Cheers,
