[PATCH v3 0/3] Introduce atomic_dec_and_lock_irqsave + refcount_dec_and_lock_irqsave()

[Sebastian Andrzej Siewior]

This patchset introduces atomic_dec_and_lock_irqsave() and
refcount_dec_and_lock_irqsave(). The individual user are not part of
this series.
The custom Alpha implementation of atomic_dec_and_lock() is removed
because the decrement operation is not a RELEASE operation (pointed out
by Peter Zijlstra).
