From da4276b8299a6544dc41ac2485d3ffca5811b3fb Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 7 Jan 2009 11:05:10 +0100 Subject: x86: offer frame pointers in all build modes CONFIG_FRAME_POINTERS=y results in much better debug info for the kernel (clear and precise backtraces), with the only drawback being a ~1% increase in kernel size. So offer it unconditionally and enable it by default.
