From 86d63363defc0b2f22288b287f75837d48b561fc Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 6 Apr 2015 22:00:38 -0500 Subject: [PATCH] powerpc/e500mc: Remove dead L2 flushing code in idle_e500.S This code can never be executed as it is only built when CONFIG_PPC_E500MC is unset, but the only CPUs that have CPU_FTR_L2CSR require CONFIG_PPC_E500MC and do not have the MSR/HID0-based nap mechanism that this file uses.
