Instead of hardcoding the remapping of IO_SPACE_LIMIT - SZ_64K, use resource_size(). However, we cannot use just IO_SPACE_LIMIT, because pci_ioremap_io() has a bug and doesn't allow remapping the last 64 KB before IO_SPACE_LIMIT, so we ensure that we do not exceed this limit. When the pci_ioremap_io() issue is fixed, this work around can be dropped. Note that this workaround already existed, since we were mapping only up to IO_SPACE_LIMIT - SZ_64K.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
