Hence I've gone through the dependencies of that object file and tried to get rid of at least some of the very odd dependencies there. (Some are being addressed also be the separately sent mem-access and vm-event patches with a similar subject.) 1: HVM: reduce domain.h include dependencies 2: HVM: reduce vcpu.h include dependencies 3: HVM: reduce vpt.h include dependencies 4: HVM: reduce vpic.h include dependencies 5: HVM: reduce vioapic.h include dependencies 6: HVM: reduce vlapic.h include dependencies 7: HVM: reduce io.h include dependencies 8: HVM: reduce hvm.h include dependencies 9: reduce mce.h include dependencies Jan
