From 1b70c5a6491dd02263e6d104b72d9b536f987021 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 7 May 2008 10:00:55 +1000 Subject: [PATCH] [POWERPC] Fix bogus paca->_current initialization When doing lockdep, I had two patches to initialize paca->_current early, one bogus, and one correct. Unfortunately both got merged as the bad one ended up being part of the main lockdep patch by mistake. This causes memory corruption at boot. This removes the offending code.
