Seriously, just add your damn fixes tree to linux-next.  If your fixes
are as perfect as you claim that one time setup is all you need to do,
and you have less work than you spent arguing on this thread already.

If it catches bugs eventually you will need to do more work, but save
others from deadling with your regression.  There is no downside for
you.
