OK, I found you disabled CONFIG_MD, which means neither dm.ko nor md.ko was built. Do you have any out-of-tree kernel modules which call either bd_claim_by_kobject or bd_claim_by_disk?
If you aren't using either of them, I'm afraid reverting the patch doesn't really solve your problem because the patched code is called only from them.
