While I was trying to insert probes on certain funcitons of interest, I had 
difficulty in expressing some functions as the wild card method was not 
helpful as the names of these function did not had any pattern.

From the objdump of the kernel, however I found that all of the functions of 
my interest was in certain address range. Hence thought this would be a nice 
feature if systemtap supports it.

Some discussion on this on the mailing list can be found.
