Thread-topic:	PVOPS Build Failure: CONFIG_PCI_XEN flag not produced

The builds are failing after pulling yesterdays 11/10 pvops tree. It appears that the CONFIG_PCI_XEN flag is not being produced by make menuconfig.

The build error is:

arch/x86/built-in.o: In function `pci_swiotlb_init':

/root/kernels/linux-2.6-xen/arch/x86/kernel/pci-swiotlb.c:54: undefined reference to `xen_wants_swiotlb'

make: *** [.tmp_vmlinux1] Error 1

Which should have been defined by:

drivers/pci/Makefile:31:obj-$(CONFIG_PCI_XEN) += xen-iommu.o

CONFIG_PCI_XEN does not get produced in the default .config file from 'make menuconfig'.

I am performing the following build steps:

cd /usr/src/kernels

git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen

cd linux-2.6-xen

git checkout origin/xen-tip/master -b xen-tip/master

make menuconfig

make

make modules_install install

Suggestions? Workarounds?

Thanks
