Add support to expose Intel V2 Extended Topology Enumeration Leaf for some new systems with multiple software-visible die within each package. Because unimplemented and unexposed leaves should be explicitly reported as zero, there is no need to limit cpuid.0.eax to the maximum value of feature configuration but limit it to the highest leaf implemented in the current code. A single clamping seems sufficient and cheaper.

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.
