From 64dec40ddee9d36d7b83f8a0513fdeaffe260a0e Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Fri, 16 Jan 2009 13:23:35 -0500 Subject: x86: define ARCH_WANT_FRAME_POINTERS Commit da4276b8299a6544dc41ac2485d3ffca5811b3fb changed a dependency for FRAME_POINTER from X86 to ARCH_WANT_FRAME_POINTERS, but didn't actually define it. This patch adds the definition for ARCH_WANT_FRAME_POINTERS. Without it, FRAME_POINTER can't be enabled on x86.
