Using SZ_4K in context of SysMMU driver is better than using PAGE_SIZE, as PAGE_SIZE might have different value on different platforms. Though it would be even better to use more specific constants, already existing in SysMMU driver. Make the code more strict by using SPAGE_ORDER and SPAGE_SIZE constants. It also makes sense, as __sysmmu_tlb_invalidate_entry() also uses SPAGE_* constants for further calculations with num_inv param, so it's logical that num_inv should be previously calculated using also SPAGE_* values.

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.
