commit 85955320929648b38168caf5fb9ffa4a95904f04

    PR909: Emit proper decls for perf probes
    
    While I still have some TODOs, it's now in a usable state for others to
    start testing...
    
    * tapset-perfmon.cxx (perf_derived_probe_group::emit_module_decls):
      Implement the code to hook up real stap handlers.
      (perf_derived_probe_group::emit_module_init): Register for real.
      (perf_derived_probe_group::emit_module_exit): Unregister.

    Translate perf events names into kernel names
    
    * tapset-perfmon.cxx (perf_builder::translate_event): New.  The event
      mapping is hard-copied from the current state of perf.
      (perf_builder::build): Call it.

commit a3cf75e6d0d589ab0922ccb0cecae6cdc480ecde
Author: Josh Stone <jistone@redhat.com>
Date:   Tue Mar 16 16:53:48 2010 -0700

    Rename perf probe points
    
    These are now the available points:
      perf.event("NAME")
      perf.event("NAME").sample(NUM)
    
    * tapset-perfmon.cxx (perf_derived_probe::perf_derived_probe): Add
      fields for the event name, type, and config.  Rewrite the probe_point
      to match the derived components
      (perf_builder::build): Parse the new fields.
      (register_tapset_perf): Adapt the match_nodes.

    Move the perf CONFIG check
    
    IMO, it's better to contain the CONFIG check inside the perf code.
    
    * tapsets.cxx (register_standard_tapsets): Always call perf register.
    * tapset-perfmon.cxx (register_tapset_perf): Do the CONFIG check here.

    Remove the old performance monitoring code.

    Modify the systemtap perf sampling internal api
    
    The only information available in the overflow interrupt is the event.
    Need to group other pieces of information needed by systemtap, so they
    can be found based on the the location of the event information.

    PR909: Runtime for Performance Event Sampling
    
    Implements a very simple sampling runtime to using the performance
    events kernel API. An perf event attribute describing the setup and a
    function to handle the counter overflows are passed into
    _stp_perf_init(). This function sets up the event on each processor.
    If successfully initialized, a pointer data structure is
    returned. When the sampling is no longer needed _stp_perf_del() is
    called to shutdown the sampling.
    
     * runtime/perf.h: Add declarations for data structures and functions
     * runtime/perf.c: Remove old perfmon runtime runtime.
       		   Add  _stp_perf_init() and _stp_perf_del() functions.
