The LPI translation cache needs to be discarded when an ITS command may affect the translation of an LPI (DISCARD, MAPC and MAPD with V=0) or the routing of an LPI to a redistributor with disabled LPIs (MOVI, MOVALL). We decide to perform a full invalidation of the cache, irrespective of the LPI that is affected. Commands are supposed to be rare enough that it doesn't matter.

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.
