From b2ea25b958968c152c6fac0594f2c9aa8b59eb8d Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Wed, 10 Dec 2008 20:16:07 +0000 Subject: [PATCH] powerpc: Convert cpu_to_l2cache() to of_find_next_cache_node() The smp code uses cache information to populate cpu_core_map; change it to use common code for cache lookup.
