As far as I can tell, in both 2.4.4-ac2 and 2.4.4, CONFIG_ITANIUM_PTCG is defined in arch/ia64/config.in, 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 fi fi Here is the recently deleted entry from Configure.help: > -Enable use of global TLB purge instruction (ptc.g) > -CONFIG_ITANIUM_PTCG > - Say Y here if you want the kernel to use the IA-64 "ptc.g" > - instruction to flush the TLB on all CPUs. Select N here if > - you're unsure. If you need that entry restored to Configure.help, we can put it back in, with a "retained orphan" note. We have been trying to prune out uneeded material from Configure.help, and this entry seemed to fit in that category. Please let us know what you need. Steven
