John David Anglin 0d3897a7f5 parisc: Implement __smp_store_release and __smp_load_acquire barriers
commit e96ebd589d upstream.

This patch implements the __smp_store_release and __smp_load_acquire barriers
using ordered stores and loads.  This avoids the sync instruction present in
the generic implementation.
