Modified Files:
        syssrc/sys/arch/acorn32/include: lock.h

Log Message:
Special locking primitives for use in Hydra kernels.  These include a cache
invalidation after every lock to ensure that changes made by other CPUs are
visible.  This has nasty performance implications, but it does allow my
Hydrated Risc PC to run printf() on all its CPUs at once without corrupting
the message buffer.
