Subject: [PATCH] ftrace: Build without frame pointers on Microblaze
Date: Mon,  4 Apr 2011 11:20:12 +0200	[thread overview]
Message-ID: <1301908812-8119-2-git-send-email-monstr@monstr.eu> (raw)
In-Reply-To: <1301908812-8119-1-git-send-email-monstr@monstr.eu>

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)
