[PATCH 01/37] locking/lockdep: Move valid_state() inside CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING

[Frederic Weisbecker]

valid_state() and print_usage*() functions are not used beyond locking
correctness checks. So move them inside the appropriate
CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING section.

Sadly the "unused function" warning wouldn't fire because valid_state()
is inline.
