The "num_tlb_lines" might not be a power-of-2 value, being 48 on Tegra210 for example. So the current way of calculating tlb_mask using the num_tlb_lines is not correct: tlb_mask=0x5f in case of num_tlb_lines=48, which will trim a setting of 0x30 (48) to 0x10.

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.
