[PATCH v6 7/9] ppc64 ftrace: disable profiling for some files

From: Torsten Duwe
Date: Mon Jan 25 2016 - 12:19:52 EST


This patch complements the "notrace" attribute for selected functions.
It adds -mprofile-kernel to the cc flags to be stripped from the command
line for code-patching.o and feature-fixups.o, in addition to "-pg"
