x86/mce: Fix RCU lockdep splats
Create an rcu_dereference_check_mce() that checks for RCU-sched read side and mce_read_mutex being held on update side. Replace uses of rcu_dereference() in arch/x86/kernel/cpu/mcheck/mce.c with this new macro. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: "H.
