This flag just caches if the IO page size is larger than the CPU PAGE_SIZE. This only needs to be checked in two places so remove the confusingly named cache. dart would like to not support paging domains at all if the IO page size is larger than the CPU page size. In this case we should ideally fail domain_alloc_paging(), as there is no point in creating a domain that can never be attached. Move the test into apple_dart_finalize_domain(). The check in apple_dart_mod_streams() will prevent the domain from being attached to the wrong dart There is no HW limitation that prevents BLOCKED domains from working, remove that test. The check in apple_dart_of_xlate() is redundant since immediately after the pgsize is checked. Remove it. Remove the variable.

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.
