From baf9ff74eda9f0efcc8a68e8a9c9d183be13a810 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 9 Oct 2012 21:16:07 +0200 Subject: MIPS: Switch over to generic sys_execve and kernel_execve. This version contains a few updates by David Daney, in particular it's now using __builtin_frame_address() instead of asm() which depending on personal taste, is slightly more appealing.
