    x86: Audit and remove any remaining unnecessary uses of module.h · eb008eb6
    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.  In the case of
    some of these which are modular, we can extend that to also include
    files that are building basic support functionality but not related
    to loading or registering the final module; such files also have
    no need whatsoever for module.h
    
    The advantage in removing such instances 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 instance for the
    presence of either and replace as needed.
    
    In the case of crypto/glue_helper.c we delete a redundant instance
    of MODULE_LICENSE in order to delete module.h -- the license info
    is already present at the top of the file.
    
    The uncore change warrants a mention too; it is uncore.c that uses
    module.h and not uncore.h; hence the relocation done there.
