[ Upstream commit1b7aebf048] cpuinfo_x86.x86_model is an unsigned type, so comparing against zero will generate a compilation warning: arch/x86/kernel/cpu/cacheinfo.c: In function 'cacheinfo_amd_init_llc_id': arch/x86/kernel/cpu/cacheinfo.c:662:19: warning: comparison is always true \ due to limited range of data type [-Wtype-limits] Remove the unnecessary lower bound check.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
