find_first_zero_bit()'s parameter 'size' is defined in bits,
not in bytes.
find_first_zero_bit() is called with size in bytes rather than bits,
which thus defines a too low upper limit, causing
dw_pcie_ep_inbound_atu() to assign iatu index #4 to both bar 4
and bar 5, which makes bar 5 overwrite the settings set by bar 4.
Since the sizes of the bitmaps are known, dynamically allocate the
bitmaps, and use the correct size when calling find_first_zero_bit().
Additionally, make sure that ep->num_ob_windows and ep->num_ib_windows,
which are obtained from device tree, are smaller than the maximum number
of iATUs (MAX_IATU_IN/MAX_IATU_OUT).

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.
