Subject: s390/sparsemem: Provide phys_to_target_node() with CONFIG_NUMA
X-Git-Tag: v6.13-rc1~206^2~44
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e89204070dac190bb38d4e4e87c9a0c88664f385;p=thirdparty%2Fkernel%2Flinux.git

s390/sparsemem: Provide phys_to_target_node() with CONFIG_NUMA

Add a trival phys_to_target_node() implementation which always returns 0 if
CONFIG_NUMA is enabled, since the s390 NUMA implementation only supports
node 0.
This is similar to memory_add_physaddr_to_nid() in order to avoid runtime
warnings.
