    kernel/padata.c: removed unused code · 815613da
    Richard Cochran authored
    By accident I stumbled across code that has never been used.  This
    driver has EXPORT_SYMBOL functions, and the only user of the code is
    pcrypt.c, but this only uses a subset of the exported symbols.
    
    According to 'git log -G', the functions, padata_set_cpumasks,
    padata_add_cpu, and padata_remove_cpu have never been used since they
    were first introduced.  This patch removes the unused code.
    
    On one 64 bit build, with CRYPTO_PCRYPT built in, the text is more than
    4k smaller.

    On another config, 32 bit, the saving is about 0.5k bytes.
