[parisc-linux] Anyone still caring about 2.4?

[Matthew Wilcox]

I was just looking at a 2.4 problem for lamont so I went back to a 2.4
tree I had lying around.  I found this diff:

        dprintk ("map_user_kiobuf: end OK\n");
        return 0;
 }

Don't remember why I made it or whether it's right.  Thought I'd throw
it out to the mailing list rather than just delete it.

"Next the statesmen will invent cheap lies, putting the blame upon 
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain
