Use scsi_add_host_with_dma() instead of scsi_add_host(). When the scsi request queue is initialized/allocated, hw_max_sectors is clamped to the dma max mapping size. Therefore, the correct device that should be used for the clamping needs to be set. The same clamping is still needed in usb-storage as hw_max_sectors could be changed there. The original clamping would be invalidated in such cases.

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.
