Hookup remap_pfn_range and vm_insert_pfn and corresponding copy and free routines with reserve and free tracking. reserve and free here only takes care of non RAM region mapping. For RAM region, driver should use set_memory_[uc|wc|wb] to set the cache type and then setup the mapping for user pte. We can bypass below reserve/free in that case.
