As far as I can tell, in both 2.4.4-ac2 and 2.4.4, CONFIG_ITANIUM_PTCG
is defined in arch/ia64/, but not offered as a setable choice.  Here
is an example from that file:

if [ "$CONFIG_MCKINLEY" = "y" ]; then
        define_bool CONFIG_ITANIUM_PTCG y
        define_int CONFIG_IA64_L1_CACHE_SHIFT 7
        bool '  Enable McKinley A-step specific code' CONFIG_MCKINLEY_ASTEP_SPECIFIC
        if [ "$CONFIG_MCKINLEY_ASTEP_SPECIFIC" = "y" ]; then
          bool '   Enable McKinley A0/A1-step specific code' CONFIG_MCKINLEY_A0_SPECIFIC

Here is the recently deleted entry from

If you need that entry restored to, we can put it back in, with
a "retained orphan" note.

We have been trying to prune out uneeded material from, and
this entry seemed to fit in that category.

Please let us know what you need.
