 I trapped the kernel when sending the signal and verified the faulting
 address. In this case it was 0x140268087 (clearly not mapped anywhere),
 where 0x40268087 would be fine and probably what the process tries to
 access.
 
 But I am not sure where to catch and fix it (nor where the pc-relative-address
 stub is generated).
 
 Should locore.s/trap.c truncate the fault address for 32bit processes
 before calling uvm_fault? Should uvm deal? Is the pc-relative addressing
 stub bogus?
