Subject: mm/bootmem: silence section mismatch warning - contig_page_data/bootmem_node_data
From: Marcin Slusarz <marcin.slusarz@xxxxxxxxx>
WARNING: vmlinux.o(.data+0x1f5c0): Section mismatch in reference from the variable contig_page_data to the variable .init.data:bootmem_node_data
The variable contig_page_data references
the variable __initdata bootmem_node_data
If the reference is valid then annotate the
variable with __init* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
