Previously, HFI instances were never disabled once enabled. A CPU in an instance only had to check during boot whether another CPU had previously initialized the instance and its corresponding data structure. A subsequent changeset will add functionality to disable instances to support hibernation. Such change will also make possible to disable an HFI instance during runtime via CPU hotplug. Enable an HFI instance from the first of its CPUs that comes online. This covers the boot, CPU hotplug, and resume-from-suspend cases. It also covers systems with one or more HFI instances (i.e., packages). Signed-off-by: Ricardo Neri <ricardo.neri-calderon@linux.intel.com> Signed-off-by: Rafael J.

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.
