    sysfs: add parameter "struct bin_attribute *" in .read/.write methods for 
sysfs binary attributes
    
    Well, first of all, I don't want to change so many files either.
    
    What I do:
    Adding a new parameter "struct bin_attribute *" in the
    .read/.write methods for the sysfs binary attributes.
    
    In fact, only the four lines change in fs/sysfs/bin.c and
    include/linux/sysfs.h do the real work.
    But I have to update all the files that use binary attributes
    to make them compatible with the new .read and .write methods.
    I'm not sure if I missed any. :(
    
    Why I do this:
    For a sysfs attribute, we can get a pointer pointing to the
    struct attribute in the .show/.store method,
    while we can't do this for the binary attributes.
    I don't know why this is different, but this does make it not
    so handy to use the binary attributes as the regular ones.
    So I think this patch is reasonable. :)
    
    Who benefits from it:
    The patch that exposes ACPI tables in sysfs
    requires such an improvement.
    All the table binary attributes share the same .read method.
    Parameter "struct bin_attribute *" is used to get
    the table signature and instance number which are used to
    distinguish different ACPI table binary attributes.
    
    Without this parameter, we need to offer different .read methods
    for different ACPI table binary attributes.
    This is impossible as there are various ACPI tables on different
    platforms, and we don't know what they are until they are loaded.
