Currently memtrace doesn't build if NUMA=n: In function ‘memtrace_alloc_node’: arch/powerpc/platforms/powernv/memtrace.c:134:6: error: the address of ‘contig_page_data’ will always evaluate as ‘true’ if (!NODE_DATA(nid) || !node_spanned_pages(nid)) ^ This is because for NUMA=n NODE_DATA(nid) points to an always allocated structure, contig_page_data. But even in the NUMA=y case memtrace_alloc_node() is only called for online nodes, and we should always have a NODE_DATA() allocated for an online node. So remove the (hopefully) overly paranoid check, which also means we can build when NUMA=n. Signed-off-by:
