Some users of pata_falcon on Q40 have IDE disks in default IDE little endian byte order, whereas legacy disks use host-native big-endian byte order as on the Atari Falcon. Add module parameter 'data_swab' to allow connecting drives with non-native data byte order. Drives selected by the data_swap bit mask will have their user data byte-swapped to host byte order, i.e. 'pata_falcon.data_swab=2' will byte-swap all user data on drive B, leaving data on drive A in native byte order. On Q40, drives on a second IDE interface may be added to the bit mask as bits 2 and 3. Default setting is no byte swapping, i.e. compatibility with the native Falcon or Q40 operating system disk format.

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.
