There isn't a total_memory identifier within this function's scope. The
patch was compile/link tested.

The platform registers the hpet clocksource too.
Instead of adding the config flag to hpet driver, how about the patch
below? Since you already check for duplication by address then adding
a check for by name too seems okay to me.

Hi Len,
On 2.6.20-rc6-mm2 my rx2600 wouldn't boot unless I reverted all changes
to drivers/acpi/tables.c. Nearly all major early boot detected ACPI tables
weren't discovered. I never had time to resolve because 2.6.20-rc6-mm3
showed up. The -mm2 problem appears corrected but the machine now crash
Eliminate arch specific memory_present calls for ia64 NUMA and x86_64 NUMA by
utilizing sparse_memory_present_with_active_regions. It was boot tested
for both arches.
