Now that we allow CPUs affected by erratum1418040to come in late, this prevents their unaffected sibblings from coming in late (or coming back after a suspend or hotplug-off, which amounts to the same thing). To allow this, we need to add ARM64_CPUCAP_OPTIONAL_FOR_LATE_CPU, which amounts to set .type to ARM64_CPUCAP_WEAK_LOCAL_CPU_FEATURE.

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.
