For both ID_AA64SMFR0_EL1.I16I64 and ID_AA64SMFR0_EL1.I8I32 we check for
the presence of the feature by looking for a specific ID value of 0x4 but
should instead be checking for the value 0xf defined by the architecture.
This had no practical effect since we are looking for values >= our define
and the only valid values in the architecture are 0b0000 and 0b1111 so we
would detect things appropriately with the architecture as it stands even
with the incorrect defines.

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.
