It implies that __alloc_vmap_area() allocates only from the global vmap space, therefore a list-head and rb-tree, which represent a free vmap space, are not passed as parameters to this function and are accessed directly from this function. Extend the __alloc_vmap_area() and other dependent functions to have a possibility to allocate from different trees making an interface common and not specific. There is no functional change as a result of this patch.

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.
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.
