  Log:
  Mega busdma API commit.
  
  Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
  Lockfunc allows a driver to provide a function for managing its locking
  semantics while using busdma.  At the moment, this is used for the
  asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
  are provided: busdma_lock_mutex() performs standard mutex operations on the
  mutex that is specified from lockfuncarg.  dftl_lock() is a panic
  implementation and is defaulted to when NULL, NULL are passed to
  bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
  when the driver ensures that bus_dmamap_load() will not be deferred.
  Drivers that do not provide their own locking can pass
  busdma_lock_mutex,&Giant args in order to preserve the former behaviour.
  
  sparc64 and powerpc do not provide real busdma_swi functions, so this is
  largely a noop on those platforms.  The busdma_swi on is64 is not properly
  locked yet, so warnings will be emitted on this platform when busdma
  callback deferrals happen.
  
  If anyone gets panics or warnings from dflt_lock() being called, please
  let me know right away.
