"lockdep: Selftest: Only do hardirq context test for raw spinlock"
disabled the execution of certain tests with PREEMPT_RT_FULL, but did
not prevent the tests from still being defined. This leads to warnings
like:
./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_12'
defined but not used [-Wunused-function]
./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_21'
defined but not used [-Wunused-function]
./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_12'
defined but not used [-Wunused-function]
./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_21'
defined but not used [-Wunused-function]
./linux/lib/locking-selftest.c:580:1: warning: 'irqsafe1_soft_spin_12'
defined but not used [-Wunused-function]
...
Fixed by wrapping the test definitions in #ifndef CONFIG_PREEMPT_RT_FULL
conditionals.

FYI: To be clearer, this should apply to all stable RT releases 3.4 and later.
