Add the cpufeature and hwcap entries to detect the presence of MTE. Any secondary CPU not supporting the feature, if detected on the boot CPU, will be parked. Add the minimum SCTLR_EL1 and HCR_EL2 bits for enabling MTE. The Normal Tagged memory type is configured in MAIR_EL1 before the MMU is enabled in order to avoid disrupting other CPUs in the CnP domain.

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.
