From ec8c27e04f89a7575ca2c4facb99152e03d6a99c Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 30 Apr 2010 06:45:36 -0700 Subject: [PATCH] mce: convert to rcu_dereference_index_check() The mce processing applies rcu_dereference_check() to integers used as array indices. This patch therefore moves mce to the new RCU API rcu_dereference_index_check() that avoids the sparse processing that would otherwise result in compiler errors. Signed-off-by: Paul E.
