    x86/kernel: Audit and remove any unnecessary uses of module.h · 186f4360
    Paul Gortmaker authored
    Historically a lot of these existed because we did not have
    a distinction between what was modular code and what was providing
    support to modules via EXPORT_SYMBOL and friends.  That changed
    when we forked out support for the latter into the export.h file.
    This means we should be able to reduce the usage of module.h
    in code that is obj-y Makefile or bool Kconfig.  The advantage
    in doing so is that module.h itself sources about 15 other headers;
    adding significantly to what we feed cpp, and it can obscure what
    headers we are effectively using.
    Since module.h was the source for init.h (for __init) and for
    export.h (for EXPORT_SYMBOL) we consider each obj-y/bool instance
    for the presence of either and replace as needed.  Build testing
    revealed some implicit header usage that was fixed up accordingly.
    Note that some bool/obj-y instances remain since module.h is
    the header for some exception table entry stuff, and for things
    like __init_or_module (code that is tossed when MODULES=n).
