Oleg Nesterov caa9ee771d [PATCH] rcu_process_callbacks: don't cli() while testing ->nxtlist 
__rcu_process_callbacks() disables interrupts to protect itself from
call_rcu() which adds new entries to ->nxtlist.

However we can check "->nxtlist != NULL" with interrupts enabled, we can't
get "false positives" because call_rcu() can only change this condition
from 0 to 1.

Tested with rcutorture.ko.
