hardirq.h: needs sched.h if using BKL
This really isn't the right thing to do, and strictly speaking we should have the BKL depth count in the thread info right next to the preempt count. The two really do go together. However, since that would involve a patch to all architectures, and the BKL is finally going away, it's simply not worth the effort to do the RightThing(tm). Just re-instate the <linux/sched.h> include that we used to get accidentally from the smp_lock.h one. This is all fallout from the same old "BKL: remove extraneous #include <smp_lock.h>" commit.
