Log message:
pull the guts of bus_space_barrier into the inline function in the header.
there's only one implementation of it on sparc64, so we shouldnt need to
iterate up a chain of bus_space_tags to get to it.
because the only argument that is used inside the function is the flags,
this can generally be inlined to a single membar opcode. this leaves that
op as membar(Sync) for now while kettenis@ thinks about what changing it
might mean.
ok miod@
