Subject: powerpc/numa: Remove redundant find_cpu_node()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8b16cd238d414b8942a23f0f753cdc57b17c231a;p=linux-beck.git

powerpc/numa: Remove redundant find_cpu_node()

Use of_get_cpu_node, which is a superset of numa.c's find_cpu_node in
a less restrictive section (text vs cpuinit).
