ksymoops (user space), kdb, kksymoops (kernel).

Both kdb and kksymoops are specifically designed to not use
relocations, they store kernel addresses as absolute numbers.  Not that
big a deal, ia64 setup can run the kallsyms tables at boot time and
relocate them.

ksymoops in user space is a bigger problem, it reads System.map.
Fixing user space will be a problem.  OTOH, the function descriptor
problem in ia64 means that ksymoops in user space gets thousands of
address mismatches between System.map and /proc/ksyms so ksymoops is
not used very much for ia64.
