From fc532f810832beb3306b42526a78f411972281c7 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Fri, 25 Jul 2008 17:50:30 -0500 Subject: [PATCH] powerpc: Fix boot problem due to AT_BASE_PLATFORM change Commit 9115d13453dee22473a1e8cacc90a8d64a9c4bc9 ("powerpc: Enable AT_BASE_PLATFORM aux vector") broke boot on 32-bit powerpc systems; we have to use PTRRELOC to initialize powerpc_base_platform this early in boot.
