Commit 625d693e9784f988371e69c2b41a2172c0be6c11 (linux-next)
"sparc64: Convert over to NO_BOOTMEM."
causes the following compile failure for sparc64 allnoconfig:
arch/sparc/mm/init_64.c:822:16: error: unused variable 'paddr'
arch/sparc/mm/init_64.c:1759:7: error: unused variable 'node'
arch/sparc/mm/init_64.c:809:12: error: 'memblock_nid_range' defined but not used
The paddr decl can easily be shuffled within the ifdef. The
memblock_nid_range is just a stub function for when NEED_MULTIPLE_NODES
is off, but the only caller is within a NEED_MULTIPLE_NODES enabled
section, so we can simply delete it.
The unused "node" is slightly more interesting. In the case of
"# CONFIG_NEED_MULTIPLE_NODES is not set" we no longer get the
definition of:
#define NODE_DATA(nid) (node_data[nid])
from arch/sparc/include/asm/mmzone.h - but instead we get:
#define NODE_DATA(nid) (&contig_page_data)
from include/linux/mmzone.h -- and since the arg is ignored,
the thing really is unused. Rather than put in a confusing
looking __maybe_unused, simply splitting the declaration
from the assignment seemed to me to be the least offensive.
