_tlbia() is a function used only on 603/603e core, ie on CPUs which don't have a hash table. _tlbia() uses the tlbia macro which implements a loop of 1024 tlbie. On the 603/603e core, flushing the entire TLB requires no more than 32 tlbie. Replace tlbia by a loop of 32 tlbie.

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.
