 * Synchronization of I/O with respect to various

 *
 * Due to the support of systems with write buffers which may
 * not be able to be turned off, this function *must* used at
 * any point in which data consistency might be required.
 *
 * Generally this means that if a memory object has multiple mappings
 * (both for I/O, as described by the handle, and the IU, via, e.g.
 * a call to ddi_dma_kvaddrp), and one mapping may have been
 * used to modify the memory object, this function must be called
 * to ensure that the modification of the memory object is
 * complete, as well as possibly to inform other mappings of
 * the object that any cached references to the object are
 * now stale (and flush or invalidate these stale cache references
 * as necessary).
 *
 * The function ddi_dma_sync() provides the general interface with
 * respect to this capability. Generally, ddi_dma_free() (below) may
 * be used in preference to ddi_dma_sync() as ddi_dma_free() calls
 * ddi_dma_sync().
 *
 * Returns 0 if all caches that exist and are specified by cache_flags
 * are successfully operated on, else -1.
 *
 * The argument offset specifies an offset into the mapping of the mapped
 * object in which to perform the synchronization. It will be silently
 * truncated to the granularity of underlying cache line sizes as
 * appropriate.
 *
 * The argument len specifies a length starting from offset in which to
 * perform the synchronization. A value of (uint_t) -1 means that the length
 * proceeds from offset to the end of the mapping. The length argument
 * will silently rounded up to the granularity of underlying cache line
 * sizes  as appropriate.
 *
 * The argument flags specifies what to synchronize (the device's view of
 * the object or the cpu's view of the object).
 *
 * Inquiring minds want to know when ddi_dma_sync should be used:
 *
 * +	When an object is mapped for dma, assume that an
 *	implicit ddi_dma_sync() is done for you.
 *
 * +	When an object is unmapped (ddi_dma_free()), assume
 *	that an implicit ddi_dma_sync() is done for you.
 *
 * +	At any time between the two times above that the
 *	memory object may have been modified by either
 *	the DMA device or a processor and you wish that
 *	the change be noticed by the master that didn't
 *	do the modifying.
 *
 * Clearly, only the third case above requires the use of ddi_dma_sync.
 *
 * Inquiring minds also want to know which flag to use:
 *
 * +	If you *modify* with a cpu the object, you use
 *	ddi_dma_sync(...DDI_DMA_SYNC_FORDEV) (you are making sure
 *	that the DMA device sees the changes you made).
 *
 * +	If you are checking, with the processor, an area
 *	of the object that the DMA device *may* have modified,
