Merge tag 'driver-core-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core merge from Greg Kroah-Hartman: "Here is the big driver core update for 3.7-rc1. A number of firmware_class.c updates (as you saw a month or so ago), and some hyper-v updates and some printk fixes as well. All patches that are outside of the drivers/base area have been acked by the respective maintainers, and have all been in the linux-next tree for a while.

+ * As we look at expanding the KVP functionality to include
+ * IP injection functionality, we need to maintain binary
+ * compatibility with older daemons.
+ *
+ * The KVP opcodes are defined by the host and it was unfortunate
+ * that I chose to treat the registration operation as part of the
+ * KVP operations defined by the host.
+ * Here is the level of compatibility
+ * (between the user level daemon and the kernel KVP driver) that we
+ * will implement:
+ *
+ * An older daemon will always be supported on a newer driver.
+ * A given user level daemon will require a minimal version of the
+ * kernel driver.
+ * If we cannot handle the version differences, we will fail gracefully
+ * (this can happen when we have a user level daemon that is more
+ * advanced than the KVP driver.
+ *
+ * We will use values used in this handshake for determining if we have
+ * workable user level daemon and the kernel driver. We begin by taking the
+ * registration opcode out of the KVP opcode namespace. We will however,
+ * maintain compatibility with the existing user-level daemon code.
