I don't agree with this.

CodingStyle says:
----------------------
The limit on the length of lines is 80 columns and this is a strongly
preferred limit.
----------------------

People should be encouraged to use 80 column lines and as well
should learn to ignore messages they don't agree with.

If people are using checkpatch prior to any scripted git am,
then just as easily they could add --ignore=LONG_LINE.
