Subject: arch/ia64/include/asm/topology.h: remove unused parent_node() macro
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5eb9e8ac9a8f8ae98ae4386357683a0b5684bb48;p=openwrt%2Fstaging%2Fblogic.git

arch/ia64/include/asm/topology.h: remove unused parent_node() macro

Commit a7be6e5a7f8d ("mm: drop useless local parameters of
__register_one_node()") removed the last user of parent_node().

The parent_node() macro in IA64(Itanium) platform is unnecessary.

Remove it for cleanup.
