commit b642c901a918a92fdd6b1167ed02dfe4c50cdd3e
Author: Stan Cox <scox@redhat.com>

    Add kprobe user probe semaphore handling.
    
    Adds stap_kprobe_process_found and stap_kprobe_mmap_found handlers
    and then the task_finder uses those to set the semaphore values.
    The probe adds user_path and user_lib which are used by the
    task_finder to decide what object to sniff.
    
    * sdt.h (STAP_SEMAPHORE): Also define for kprobes.
    * tapsets.cxx (dwarf_derived_probe): Add user_path and user_lib.
    (dwarf_derived_probe::join_group): Enable task finder for kprobes.
    (dwarf_derived_probe::dwarf_derived_probe): Set user_path and
    user_lib.
    (dwarf_derived_probe_group::emit_module_decls): Emit
    stap_kprobe_mmap_found, sdt_sem_offset, sdt_sem_address, pathname,
    and finder declarations.  Emit stap_kprobe_process_found and
    stap_kprobe_mmap_found.
    (dwarf_derived_probe_group::emit_module_init): Setup task finder.
    (sdt_query::convert_location): Remove TOK_LIBRARY token.
    (dwarf_builder::build): Set user_path and user_lib.
    (kprobe_derived_probe): Add path and library.
    (kprobe_builder::build): Get process and library params
