>> WARNING: modpost: vmlinux.o(.text+0xa47e1): Section mismatch in reference from the function __next_node() to the variable .init.data:numa_nodes_parsed
The function __next_node() references
the variable __initdata numa_nodes_parsed.
This is often because __next_node lacks a __initdata
annotation or the annotation of numa_nodes_parsed is wrong.
