kmap() is being deprecated and will break uses of device dax after PKS protection is introduced.[1] These uses of kmap() in the SIW driver are thread local. Therefore kmap_local_page() is sufficient to use and will work with pgmap protected pages when those are implemnted. There is one more use of kmap() in this driver which is split into its own patch because kmap_local_page() has strict ordering rules and the use of the kmap_mask over multiple segments must be handled carefully. Therefore, that conversion is handled in a stand alone patch. Use kmap_local_page() instead of kmap() in the 'easy' cases.
