Rao" 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 Signed-off-by: Naveen N.
