I care more about files being consistent internally than I do about
adhering to a new 100 column rule.

With very few exceptions, pcie-designware-host.c fits in 80 columns.
I think there's no point in adding a comment using 100 columns.  That
leadds to either a window sized to accommodate 100 columns, where 20
columns are wasted for all the existing code and comments, or a window
sized for 80 columns, where the new comment looks ugly.  Neither is
attractive.
