The systemtap.sample/poll_map.stp test built with the current systemtap
translator (20061222) dies on FC6 machines. The test is getting a NULL
dereference when running:
BUG: unable to handle kernel NULL pointer dere8 printing eip:

*pde = 00000000
Oops: 0000 [#1]

EFLAGS: 00210202 (2.6.18-1.2868.fc6 #1)
Commenting out the entire probe kernel.function( "sys_*" ) avoids crashing the
machine. However, just commenting out the body of the probe kernel.function(
"sys_*" ) still crashes.
