From: Leon Romanovsky <leonro@nvidia.com> Alpha doesn't need struct *page and can perform mapping based on physical addresses. So convert it to implement new .map_phys callback. As part of this change, remove useless BUG_ON() as DMA mapping layer ensures that right direction is provided.
After the changes in v1 this runs fine on Alpha. I've tested this on an ES40 Alphaserver during load (build kernel and unpack tar files). The v1 patch fixes the errors seen in the first revision of this patch. Tested-by: Magnus Lindholm <linmag7@gmail.com>
