Add feature enumeration to identify a processor with Intel Hybrid Technology: one in which CPUs of more than one type are the same package. On a hybrid processor, all CPUs support the same homogeneous (i.e., symmetric) instruction set. All CPUs enumerate the same features in CPUID. Thus, software (user space and kernel) can run and migrate to any CPU in the system as well as utilize any of the enumerated features without any change or special provisions. The main difference among CPUs in a hybrid processor are power and performance properties.

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.
