From fa5c11b790f9e18ec6f69680c4aa728157aef5f5 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Fri, 28 Mar 2014 16:40:39 +1100 Subject: [PATCH] powerpc: Remove dead code in sycall entry In: commit 742415d6b66bf09e3e73280178ef7ec85c90b7ee Author: Michael Neuling powerpc: Turn syscall handler into macros We converted the syscall entry code onto macros, but in doing this we introduced some cruft that's never run and should never have been added. This removes that code.
