thread_info part 3: heads.
a) in smp_lock.h #include of sched.h and spinlock.h moved under
#ifdef CONFIG_LOCK_KERNEL.
b) interrupt.h now explicitly pulls sched.h (not via smp_lock.h from
hardirq.h as it used to)
c) in two more places we need changes to compensate for (a) - one place in
arch/sparc needs string.h now and hardirq.h needs forward declaration of
task_struct.
d) thread_info-related helpers in sched.h and thread_info.h put under
ifndef __HAVE_THREAD_FUNCTIONS. Obviously safe.
That ends changes in generic parts of tree. And now we can get m68k in
there - that will be localized to asm-m68k and arch/m68k.
As far as I can see that's the minimally intrusive header changes needed
to avoid problems - better than variant with splitting sched.h as in m68k CVS.
