ATA devices (struct ata_device) have a max_sectors field which is configured internally in libata. This is then used to (re)configure the associated sdev request queue max_sectors value from how it is earlier set in __scsi_init_queue(). In __scsi_init_queue() the max_sectors value is set according to shost limits, which includes host DMA mapping limits. Cap the ata_device max_sectors according to shost->max_sectors to respect this shost limit.

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.
