Subject: ACPI / NUMA: add a stub function for node_to_pxm()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4f0455cf6f23800c78265c88922c6afd875d08a7;p=linux.git

ACPI / NUMA: add a stub function for node_to_pxm()

There is already a stub function for pxm_to_node but conversion to the
other direction is missing.

It will be used by Microsoft Hypervisor code later.
