Right, cache_disable() should be called to do the proper
job, i.e. cache disabling and flushing.

OK, we can wait for more comments but if there are no other architectural
drawbacks I can't think of I'm willing to test it on
SPEAr achitecture as well. Actually I have always thought about
enabling dcache, but too lazy to implement/verify it :-(
