    mprotect.2: Remove legacy BSD text
    
    This text dates to the BSD 4.4 import and is misleading.  The mprotect
    syscall acts on page granularity and breaks up mappings as required to
    do so.
    
    Note that with the addition of non-transparent superpages (aka
    largepages) the size of a page at a given address may vary.  This
    commit does not attempt to address the lack of documentation of this
    feature.
