The December 2022 edition of the Intel Instruction Set Extensions manual defined that the split lock disable bit in the IA32_CORE_CAPABILITIES MSR is (and retrospectively always has been) architectural. Remove all the model specific checks except for Ice Lake variants which are still needed because these CPU models do not enumerate presence of the IA32_CORE_CAPABILITIES MSR.

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.
