From 03491c92932b8d2dab1bb298e0122ff6d39680af Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 23 May 2007 13:58:19 -0700 Subject: i386: fix early usage of atomic_add_return and local_add_return on real i386 The check (boot_cpu_data.x86 == 3) in atomic_add_return() and local_add_return() fails, when those operations are used before boot_cpu_data is filled in. Change the check to (boot_cpu_data.x86 <= 3) to fix this.
