init_thread_group_l1_cache_map() initializes the per-cpu cpumask thread_group_l1_cache_map with the core-siblings which share L1 cache with the CPU. Make this function generic to the cache-property (L1 or L2) and update a suitable mask. This is a preparatory patch for the next patch where we will introduce discovery of thread-groups that share L2-cache. No functional change. Signed-off-by: Gautham R.

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.
