I'm stepping up to assist with the genwqe_card driver just now, since we (ibm) missed some of the last patches that went in. I'll add myself to maintainers file.

Can your forward it to Greg together with whatever other changes are pending for the driver? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
