Out of the 707 lines in atomic.h only 25 are wider than 100 chars - and the max 
length is 104 chars.

If that's too then there's a few more things we could do - for example the 
attached patch renames a (very minor) misnomer to a shorter name and thus saves on 
the longest lines, the column histogram now looks like this:

    79 4
    80 7
    81 3
    82 9
    84 4
    85 2
    86 3
    87 1
    88 4
    89 13
    90 7
    91 20
    92 18
    93 12
    94 11
    96 5

I.e. the longest line is down to 96 columns, and 99% of the file is 94 cols or 
shorter.

Is this still too long?

Thanks,

	Ingo

Subject: [PATCH] locking/atomics: Shorten the __atomic_op() defines to __op()

The __atomic prefix is somewhat of a misnomer, because not all
APIs we use with these macros have an atomic_ prefix.

This also reduces the length of the longest lines in the header,
making them more readable on PeterZ's terminals.
