Subject: [PATCH 0/4] locking/rt: Add sparse annotation PREEMPT_RT's locking.

Hi,

the series adds sparse annotation to PREEMPT_RT's locking which
substitutes spinlock_t and rwlock_t.
The way local_lock_t is implemented, sparse annotation works for
PREEMPT_RT due its spinlock_t usage but not for !PREEMPT_RT because it
is just preempt_disable().
