From: Jason Gunthorpe <jgg at mellanox.com> DMA_SHARED_BUFFER can not be enabled by the user (it represents a library set in the kernel). The kconfig convention is to use select for such symbols so they are turned on implicitly when the user enables a kconfig that needs them. Otherwise the XEN_GNTDEV_DMABUF kconfig is overly difficult to enable.

Hey Jeremy, Please pull from devel/pat (based off your xen/dom0/core tree) which has one patch: Konrad Rzeszutek Wilk (1): xen/pat: make pte_flags(x) a pvops function. which is neccessary for the drivers/gpu/drm/radeon driver to work properly with AGP based cards (which look to be the only ones that try to set WC on pages). Also please pull from devel/kms.fixes-05 (based off your
