Subject: Fix a race accessing oops_in_progress
From: Huang Ying <ying.huang@xxxxxxxxx>
Fix a race condition accessing oops_in_progress. Which may be changed on
multiple CPU simultaneously, but it is changed via non-atomic operation
++/--. This patch changes the definition of oops_in_process from int to
atomic_t, and accessing method to atomic operations.
