At this point I think the only way to make further progress is to
actually push this stuff into the kernel on top of the BKL removal
patches for the drivers and see what happens. Something will no doubt
break but we can try and nail them in time or if not revert the series
and try again next kernel.
The big nasty remaining after this is drivers/serial, which probably
wants some serious reconstructive surgery to use kfifo etc. Either way
its an independent problem to the stuff this lot tackles.
So this series
