enable ACPI/NUMA for HP ZX1 config
PATCH 1/1 enable ACPI/NUMA for HP ZX1 config
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
