Either run the command "stepping" at the EFI prompt (you can download
stepping.efi from QuAD), or check /proc/cpuinfo within the OS.  The revision
entry tells which stepping:

Revision 0 = Ax stepping
Revision 1 = B0 stepping
Revision 2 = B1 stepping
Revision 3 = B2 stepping
Revision 4 = B3 stepping
Revision 5 = C0 stepping

Is there an easy way to tell what stepping your CPU supports?

Actually, CONFIG_ITANIUM_PTCG is still required if you have systems with
Itanium
processor steppings less than B3. I still have some of these and I'm sure
there are
quite a few others out there who still do as well.

Alan,

The following three Configure.help entries have been confirmed dead, or
not needing help by Keith Owens.

The last of these, CONFIG_IA64_AZUSA_HACKS,  is listed by Keith as
removed by a 2.4.2-ia64-010228 patch, but it still appears in 2.4.3-ac14.
