* Description:

* started using sg_miter_start(). A stopped iteration can be
* resumed by calling sg_miter_next() on it. This is useful when
* resources (kmap) need to be released during iteration.
*

* that don't need flush_kernel_dcache_page().
*
* Context:
* IRQ disabled if the SG_MITER_ATOMIC is set. Don't care otherwise.
