[Linux-ia64] [PATCH] 2.4.3-ac14 remove three IA-64 related orphans from Configure.help

[Steven Cole]

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.

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.

[Hall, Jenna S]

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

There is a stepping.efi command.  We include it in the TurboLinux Beta.  If
you need a copy let me know.

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:

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.

[Chris McDermott]

Steven,

You are correct, arch/ia64/config.in now sets CONFIG_ITANIUM_PTCG,
based on the user-setable choices CONFIG_ITANIUM_?STEP_SPECIFIC
and CONFIG_ITANIUM_B?_SPECIFIC. So, assuming the user gets those
right, they'll get the correct value for CONFIG_ITANIUM_PTCG and the
correct behavior on their system. Since this config option is temporary
anyway (only required for early processor steppings) and since it's
already been pulled out of Configure.help (I think cleaning this file up
is a good idea), I would say leave it out.

Configure.help is designed for humans to query what an option does
while they are configuring the system.  CONFIG_ITANIUM_PTCG is a
derived setting, humans have no direct control over it and it never
appears on a config menu.  Help text is not required for derived config
settings and is discouraged.
