Currently PCC mailbox controller sets con_priv in each channel to hold the pointer to pcct subspace entry it corresponds to. The mailbox user will then fetch this pointer from the channel descriptor they get when they request for the channel. Using that pointer they then parse the pcct entry again to fetch all the information about shared memory region. In order to remove individual users of PCC mailbox parsing the PCCT subspace entries to fetch same information, let us consolidate the same in pcc mailbox controller by parsing all the shared memory region information into a structure that can also hold the mbox_chan pointer it represent. This can then be used as main PCC mailbox channel pointer that we can return as part of pcc_mbox_request_channel instead of standard mailbox channel pointer.

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.
