Right now we have these variables that impact the PAT initialization sequence: pat_disabled boot_cpu_done pat_initialized init_cm_done Some have a pat_ prefix, some not, and the naming is random, which makes their purpose rather opaque. Name them consistently and according to their role: pat_disabled pat_bp_initialized pat_bp_enabled pat_cm_initialized Also rename pat_bsp_init() => pat_bp_init(), to use the canonical abbreviation. Also add a warning for double calls of init_cache_modes(), the call chains leading to this are complex and I couldn't convince myself that we never call this function twice - so utilize the flag for a debug check. No change in functionality intended. Signed-off-by: Ingo Molnar <mingo@kernel.org>
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.
