Re: [XEN RFC PATCH 09/40] xen/x86: Move numa_add_cpu_node to common

Hi Wei,

This function will be reused by Arm later, so we move it
from arch/x86 to common. But we keep cpu_to_node and
node_to_cpumask to x86 header file. Because cpu_to_node and
node_to_cpumask have different implementation for x86 and Arm.
We will move them to common header file when we change the Arm
implementation in later patches.

AFAICT, the Arm helpers are gated by !CONFIG_NUMA and the ones in common code will be gated by CONFIG_NUMA. So I am not quite too understand why they can't be moved now. Can you clarify it?
