Subject: numa, cpumask: move numa_node_id default implementation to topology.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=082edb7bf443eb8eda15b482d16ad9dd8137ad24;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

numa, cpumask: move numa_node_id default implementation to topology.h

Impact: cleanup, potential bugfix

Not sure what changed to expose this, but clearly that numa_node_id()
doesn't belong in mmzone.h (the inline in gfp.h is probably overkill, too).
