From c44e8d5e47b8ba672440b92eab0735628469116c Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Sat, 30 Dec 2006 00:43:59 +0900 Subject: [MIPS] prom_free_prom_memory cleanup Current prom_free_prom_memory() implementations are almost same as free_init_pages(), or no-op. Make free_init_pages() extern (again) and make prom_free_prom_memory() use it.
