As pointed out by David Miller the current page_pool implementation stores dma_addr_t in page->private. This won't work on 32-bit platforms with 64-bit DMA addresses since the page->private is an unsigned long and the dma_addr_t a u64. A previous patch is adding dma_addr_t on struct page to accommodate this. This patch adapts the page_pool related functions to use the newly added struct for storing and retrieving DMA addresses from network drivers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
