[Bug tapsets/11955] New: signal tapsets don't match

["andi-bz at firstfloor dot org" <sourceware-bugzilla at sourceware dot org>]

Several of the probes in the signal tapset don't resolve to the kernel source.
Confirmed with 2.6.35 and 2.6.32

e.g.

probe signal.send { 
        if (sig == 7)
                printf("sending SIGBUS to %s\n", pid_name) 
}
probe signal.handle { 
        if (sig == 7) 
                printf("SIGBUS  %s, code %x handler %x\n", execname(),  
                        sig_code, @cast(ka_addr, "struct sigaction")->sa_handler)
} 

gives
