Linux kernel source tree
f171f9e409
Currently (as of DDI0487H.a) the architecture defines the vector length control field in ZCR and SMCR as being 4 bits wide with an additional 5 bits reserved above it marked as RAZ/WI for future expansion. The kernel currently attempts to anticipate such expansion by treating these extra bits as part of the LEN field but this will be inconvenient when we start generating the defines and would cause problems in the event that the architecture goes a different direction with these fields. Let's instead change the defines to reflect the currently defined architecture, we can update in future as needed. No change in behaviour should be seen in any system, even emulated systems using the maximum allowed vector length for the current architecture.

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.
