From 3d41e0f6d91cedcab08dff2f5e148b20c87a7432 Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Tue, 28 Jun 2011 09:54:46 +0000 Subject: [PATCH] powerpc: mem_init should call memblock_is_reserved with phys_addr_t This has been broken for a while but hasn't been an issue until now because nobody was reserving regions at high addresses.
