From f4919963922f2d24a47e73046d89b27b54f74e92 Mon Sep 17 00:00:00 2001 From: Zhenhua Luo Date: Sun, 12 Jun 2016 17:02:34 +0800 Subject: binutils: fix the incorrect assembling for ppc wait instruction The wait mnemonic for ppc targets is incorrectly assembled into 0x7c00003c due to duplicated address definition with waitasec instruction. The issue causes kernel boot calltrace for ppc targets when wait instruction is executed.
