From 4b550488f894c899aa54dc935c8fee47bca2b7df Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 11 Oct 2007 23:46:08 +0100 Subject: [MIPS] Deforest the function pointer jungle in the time code. Hard to follow who is pointing what to where and why so it's simply getting in the way of the time code renovation.
