I made some time for this one. We'll see about the pairing one
(hopefully trivial? but I'm not sure if there's value in merging without
users).

Thanks. I only added one trivial fixup that checkpatch.pl's spelling.txt
(what??) caught:

diff --git a/drivers/mtd/nand/nand_base.c b/drivers/mtd/nand/nand_base.c

I added a small note in the merge commit about the BBT changes you made.
That's an especially fragile piece of code I think (and used by every
NAND driver), but it looked OK to me.
