rdmavt expects a uniform size on all umem SGEs which is currently at PAGE_SIZE. Adapt to a umem API change which could return non-uniform sized SGEs due to combining contiguous PAGE_SIZE regions into an SGE. Use for_each_sg_page variant to unfold the larger SGEs into a list of PAGE_SIZE elements. Additionally, purge umem->page_shift usage in the driver as its only relevant for ODP MRs. Use system page size and shift instead. Reviewed-by: Michael J.

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.
