Yes, and to be clear this change doesn't preclude including the PCI code. I was just looking to remove code from my VMs that aren't using PCI devices. Regards, Jason

[PATCH 0/2] Remove Xen PVH dependency on PCI
A Xen PVH domain doesn't have a PCI bus or devices, so it doesn't need PCI support built in. Currently, XEN_PVH depends on XEN_PVHVM which depends on PCI. The first patch introduces XEN_PVHVM_GUEST as a toplevel item and changes XEN_PVHVM to a hidden variable. This allows XEN_PVH to depend on XEN_PVHVM without PCI while XEN_PVHVM_GUEST depends on PCI. The second patch moves XEN_512GB to clean up the option nesting.
