Tony,
Bjorn/Alex cleaned up IA64_HP_ZX1 to also support SX1000 as well.
I suspect NUMA was introduced later and HP forgot to update
the ZX1/SX1000 config to also support NUMA. ACPI support
just seems to have been overlooked since it's required for
HP platforms.
How would you prefer to handle ACPI_NUMA?
Instead of adding more machines to change the default,
I suggest the default be "Y" with no coniditions (as proposed below).
Given the "depends NUMA", it means the user already said Y to NUMA,
this only applies if ia64 or x86_64, and I don't expect any
performance impact in the ACPI code path.
thanks,
grant
