ftrace: Build without frame pointers on Microblaze
Microblaze doesn't need/support FRAME_POINTERS in order to have a working function tracer. The patch remove Kconfig warning. Warning log: warning: (LOCKDEP && FAULT_INJECTION_STACKTRACE_FILTER && LATENCYTOP && FUNCTION_TRACER && KMEMCHECK) selects FRAME_POINTER which has unmet direct dependencies (DEBUG_KERNEL && (CRIS || M68K || FRV || UML || AVR32 || SUPERH || BLACKFIN || MN10300) || ARCH_WANT_FRAME_POINTERS) Signed-off-by: Michal Simek <monstr@monstr.eu> Link: http://lkml.kernel.org/r/1301908812-8119-2-git-send-email-monstr@monstr.eu CC: Frederic Weisbecker <fweisbec@gmail.com> CC: Ingo Molnar <mingo@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
