From 96f1bb8a412aec3fc16306ef07c5bdb426edb615 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Tue, 22 Apr 2008 10:50:27 +1000 Subject: [PATCH] [POWERPC] Add strncmp to arch/ppc Commit 0119536cd314ef95553604208c25bc35581f7f0a added an assembly version of strncmp to PowerPC. However, it changed a common header file between arch/ppc and arch/powerpc without adding strncmp to arch/ppc. This fixes that omission so that arch/ppc links again.
