mainlining shenanigans

Finally the code handles the IPA memory region array in the configuration data without assuming it is indexed by region ID. Get rid of the array index designators where these arrays are initialized. As a result, there's no more need to define an explicitly undefined memory region ID, so get rid of that. Change ipa_mem_find() so it no longer assumes the ipa->mem[] array is indexed by memory region ID. Instead, have it search the array for the entry having the requested memory ID, and return the address of the descriptor if found. Otherwise return NULL. Stop allowing memory regions to be defined with zero size and zero canary value. Check for this condition in ipa_mem_valid_one(). As a result, it is not necessary to check for this case in ipa_mem_config(). Finally, there is no need for IPA_MEM_UNDEFINED to be defined any more, so get rid of it.

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.
