In that case, just assume the current RA. This allows us to get samples of frequent callers of e.g. GLIBC memset().

For kernelspace, the already existing unwind function is utilized that uses kallsyms to quickly find the beginning of functions. For userspace a new function was added that examines code at and before the pc.
