commit 3d7c194b7c9ad414264935ad4f943a6ce285ebb1 upstream. The block layer forces a minimum segment size of PAGE_SIZE, so a segment can be too big for the ADMA table, if PAGE_SIZE >= 64KiB. Fix by writing multiple descriptors, noting that the ADMA table is sized for 4KiB chunks anyway, so it will be big enough.

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.
