Btw, I think we should kill that stupid <linux/tracehook.h> layer
entirely.  It consists of a few relatively useful function which should
just be renamed to ptrace_* and moved to ptrace.c, and a lot of entirely
pointless wrappers which generally have only a single user, and often
tons of arguments that aren't actually used.
