    Subject[PATCH 0/3] powerpc: remove unused modular code from non-modular drivers
    Date
    My ongoing audit looking for non-modular code that needlessly uses
    modular macros (vs. built-in equivalents) and/or has dead code
    relating to module unloading that can never be executed led to the
    creation of these three powerpc related commits.

    One is of the trivial kind, where we substitute in the non-modular
    versions that CPP would have put in place anyway, resulting in no
    actual changes, even at the binary output level.

    The other two are almost as trivial. In addition to the above, we
    toss out the __exit function registered by module_exit, since that
    will never get called for non modular code/drivers.

    For anyone new to the underlying goal of this cleanup, we are trying to
    not use module support for code that can never be built as a module since:

    (1) it is easy to accidentally write unused module_exit and remove code
    (2) it can be misleading when reading the source, thinking it can be
    modular when the Makefile and/or Kconfig prohibit it
    (3) it requires the include of the module.h header file which in turn
    includes nearly everything else, thus adding to CPP overhead.
    (4) it gets copied/replicated into other code and spreads like weeds.

    Build tested on v4.6-rc1 to ensure no silly typos that would break
    compilation crept in.
