From: "Naveen N. Rao" <naveen.n....@linux.vnet.ibm.com>
Fix two issues with kprobes.h on BE which were exposed with the optprobes work:
- one, having to do with a missing include for linux/module.h for
MODULE_NAME_LEN -- this didn't show up previously since the only users of
kprobe_lookup_name were in kprobes.c, which included linux/module.h
through other headers, and
- two, with a missing const qualifier for a local variable which ends up
referring a string literal. Again, this is unique to how
kprobe_lookup_name is being invoked in optprobes.c
