      return pfn from direct_access, for XIP · 30afcb4b
      Jared Hulbert authored
      Alter the block device ->direct_access() API to work with the new
      get_xip_mem() API (that requires both kaddr and pfn are returned).
      Some architectures will not do the right thing in their virt_to_page() for use
      by XIP (to translate from the kernel virtual address returned by
      direct_access(), to a user mappable pfn in XIP's page fault handler.
      However, we can't switch it to just return the pfn and not the kaddr, because
      we have no good way to get a kva from a pfn, and XIP requires the kva for its
      read(2) and write(2) handlers.  So we have to return both.
