* Synchronization of I/O with respect to various
* caches and system write buffers.
*
* Done at varying points during an I/O transfer (including at the
* removal of an I/O mapping).
*
* 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,
* you use ddi_dma_sync(....DDI_DMA_SYNC_FORCPU) (you are
* making sure that the processor(s) will see the changes
