In my point of view there are two commits there that are really necessary:

Gustavo Padovan (2):
      Bluetooth: report the right security level in getsockopt

Johan Hedberg (2):
      Bluetooth: mgmt: Fix device_connected sending order

They fix a userspace breakage caused by:

Author: Marcel Holtmann <marcel@xxxxxxxxxxxx>
Date:   Mon Feb 20 21:24:37 2012 +0100

    Bluetooth: Always enable management interface
    
    The management interface API has reached stable version 1.0 and thus
    it can now be always enabled. All future changes will be made backwards
    compatible.

This cause no crash, but it make bluetooth keyboards stop to work with Linux.
This a serious breakage IMO. I really would like to see at least these two
patches in. The other fixes can wait.
