From 27d1149667352772240655b65372a4294f992ea7 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Wed, 13 Jul 2016 09:14:40 +0800 Subject: [PATCH] powerpc/32: Remove RELOCATABLE_PPC32 It is seldom used in the kernel code and can be easily replaced by either RELOCATABLE or PPC32. So there is no reason to keep a separate kernel option for this.
