When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
Fix a total of 227 warnings like these:
drivers/net/ethernet/brocade/bna/bna_enet.c:519:3: warning: cast from 'void (*)(struct bna_ethport *, enum bna_ethport_event)' to 'bfa_fsm_t' (aka 'void (*)(void *, int)') converts to incompatible function type [-Wcast-function-type-strict]
bfa_fsm_set_state(ethport, bna_ethport_sm_down);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The bna state machine code heavily overloads its state machine functions,
so these have been separated into their own sets of structs, enums,
typedefs, and helper functions. There are almost zero binary code changes,
all seem to be related to header file line numbers changing, or the
addition of the new stats helper.
Important to mention is that while I was manually implementing this changes
I was staring at this[2] patch from Kees Cook. Thanks, Kees. :)

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.
