Because some endpoint controllers have requirements on the alignment of the controller physical memory address that must be used to map a RC PCI address region, the map PCI start address is not necessarily the desired PCI base address to be mapped. This can result in map_pci_addr being lower than pci_addr as documented. This results in map_size covering the range map_pci_addr..pci_addr+pci_size. The old text had the pci_addr twice instead of map_pci_addr..pci_addr, so replace the erroneous kerneldoc string to reflect the actual range.

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 reStructuredText 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.
