From 27609a42ee5486b8d132ece24dde6f7524d67df3 Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Mon, 10 Oct 2011 10:50:41 +0000 Subject: [PATCH] powerpc: Whitespace/comment changes to tlb_low_64e.S I happened to comment this code while I was digging through it; we might as well commit that. I also made some whitespace changes - the existing code had a lot of unnecessary newlines that I found annoying when I was working on my tiny laptop. No functional changes.
