Niklas Cassel 16b17cad09 misc: pci_endpoint_test: Handle 64-bit BARs properly
A 64-bit BAR consists of a BAR pair, where the second BAR has the
upper bits, so we cannot simply call pci_ioremap_bar() on every single
BAR index.

The second BAR in a BAR pair will not have the IORESOURCE_MEM resource
flag set. Only call ioremap on BARs that have the IORESOURCE_MEM
resource flag set.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
