------------------

From: Cong Wang <xiyou.wangcong@xxxxxxxxx>

commit 650275dbfb2f4c12bc91420ad5a99f955eabec98 upstream.

drivers/parisc/iommu-helpers.h:62: error: implicit declaration of function 'prefetchw'
make[3]: *** [drivers/parisc/sba_iommu.o] Error 1

drivers/parisc/iommu-helpers.h needs to #include <linux/prefetch.h>
where prefetchw is declared.
