Legacy Ion driver and SPARSEMEM for carveout regions results in invalid page structures breaking page_to_pfn(). This can be temporarily resolved with SPARSEMEM_VMEMMAP until the Ion driver is refactored and can be reinvestigated. At that time if it can be solved, or maybe correct this issue utilizing less resources than SPARSEMEM_VMEMMAP requires. The ABI does not change so we have the flexibility to adjust this configuration.

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.
