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.
