This patch in linux-next breaks numa detection. numa_init() will zero
numa_meminfo. If acpi_numa_init() does not call early_parse_srat(), we will
have no memory numa info.

Thanks,
Shaohua

Hum, yes, I missed this one. :)

Briefly seeing the code, I think moving the following code to 
early_parse_srat()
will fix it, right? :)

	memset(&numa_meminfo, 0, sizeof(numa_meminfo));

I'll send a patch to fix it.

Thanks. :)
