These ioctls allow userspace to load custom programs into the ISP, which: a) Seems dangerous b) Cannot be used by opensource userspace since there is no FOSS code to create such programs b) These seem to be unused even by the Android closed source camera code (they don't show up in a strace of the camera app) So removing these seems be a good idea. Another reason to remove these is that atomisp_acc_map() is the only user of the userptr functionality in hmm_alloc(), so it gets in the way of further cleanups / simplification of the hmm code.

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.
