* ftrace: store mcount address in rec->ipAbhishek Sagar2008-06-231-14/+7
| | | | | | | | | | | | Record the address of the mcount call-site. Currently all archs except sparc64 record the address of the instruction following the mcount call-site. Some general cleanups are entailed. Storing mcount addresses in rec->ip enables looking them up in the kprobe hash table later on to check if they're kprobe'd.
