The copy buffer is implemented as a real address in the nest which is translated from EA by copy, and used for memory access by paste. This requires that it be invalidated by TLB invalidation. TLBIE does invalidate the copy buffer, but TLBIEL does not. Add cp_abort to the tlbiel sequence.

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.
