From dcdf3a293522e6ef09d8b3650ac1ceec56438e5d Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Tue, 18 Nov 2008 21:25:17 +0100 Subject: m68k: Add helper function handle_kernel_fault() Add helper function handle_kernel_fault() in signal.c, so frame_extra_sizes can become static, and to avoid future code duplication.
