Subject: [PATCH] ia64: rename cache_show to topology_cache_show

Fenguang Wu has reported the following compile time issue
arch/ia64/kernel/topology.c:278:16: error: conflicting types for 'cache_show'
include/linux/slab.h:224:5: note: previous declaration of 'cache_show' was here

which has been introduced by 749c5415 (memcg: aggregate memcg cache
values in slabinfo). Let's rename ia64 local function to prevent from
the name conflict.
