From 25708a5fe7467dcc69d9b92c1701aad4a0c71887 Mon Sep 17 00:00:00 2001 From: John Kacur Date: Mon, 12 Oct 2009 22:44:40 +0200 Subject: blackfin: Remove the BKL from sys_execve This looks like a cut-and-paste job. For example, compare this function to sys_execve in arch/x86/kernel/process_64.c and it is almost line by line the same, except the one in x86 nolonger has the big kernel lock. All of the functions called between the lock are generic and not specific to blackfin - thus, I believe it is safe to remove the bkl here.
