From 2b2695a8d85593ec0253f7fdbeea1e18f0f9e5e2 Mon Sep 17 00:00:00 2001 From: Mihai Caraman Date: Wed, 20 Aug 2014 16:09:04 +0300 Subject: [PATCH] powerpc/booke: Revert SPE/AltiVec common defines for interrupt numbers Book3E specification defines shared interrupt numbers for SPE and AltiVec units. Still SPE is present in e200/e500v2 cores while AltiVec is present in e6500 core. So we can currently decide at compile-time which unit to support exclusively. As Alexander Graf suggested, this will improve code readability especially in KVM. Use distinct defines to identify SPE/AltiVec interrupt numbers, reverting c58ce397 and 6b310fc5 patches that added common defines.
