/*
* In principle, a Linux kernel for the VM could
* selectively define the virtual instructions
* as inline assembler macros, but for a first pass,
* we'll use subroutines for both the VM and the native
* kernels. It's costing a subroutine call/return,
* but it makes for a single set of entry points
* for tracing/debugging.
