Change ipa_mem_valid() to iterate over the entries using a u32 index variable rather than using a memory region ID. Use the ID found inside the memory descriptor rather than the loop index. Change ipa_mem_size_valid() to iterate over the entries but without assuming the array index is the memory region ID. "Empty" entries will have zero size; and we'll temporarily assume such entries have zero offset as well (they all do, currently). Similarly, don't assume the mem[] array is indexed by ID in ipa_mem_config(). There, "empty" entries will have a zero canary count, so no special assumptions are needed to handle them correctly.

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.
