The cma_declare_contiguous_nid code was refactored by commitc009da4258("mm, cma: support multiple contiguous ranges, if requested"), so that it could use an internal function to attempt a single range area first, and then try a multi-range one. However, that meant that the actual base address used for the !fixed case (base == 0) wasn't available one level up to be printed in the informational message, and it would always end up printing a base address of 0 in the boot message. Make the internal function take a phys_addr_t pointer to the base address, so that the value is available to the caller.

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.
