normally yes - but this is a special case: there's existing overlap with
other DMAR changes in irq/sparseirq (intr-remap and ioapic unification
changes), so these followups have to go there too. Also, since they
change the generic PCI code it's better they live in a generic topic to
begin with. The full stack of pending changes is:

0f48966: dmar: fix dmar_parse_dev() devices_cnt error condition check
2283240: dmar: use list_for_each_entry_safe() in dmar_dev_scope_init()
3f1fdb3: dmar: initialize the return value in dmar_parse_dev()
f12c73e: dmar: fix using early fixmap mapping for DMAR table parsing
1cb1158: x64, x2apic/intr-remap: disable DMA-remapping if Interrupt-remapping is detected (temporary quirk)
2ae2101: x64, x2apic/intr-remap: Interrupt remapping infrastructure
fe962e9: x64, x2apic/intr-remap: Queued invalidation infrastructure (part of VT-d)
ad3ad3f: x64, x2apic/intr-remap: parse ioapic scope under vt-d structures
2d6b5f8: x64, x2apic/intr-remap: Fix the need for RMRR in the DMA-remapping detection
aaa9d1d: x64, x2apic/intr-remap: use CONFIG_DMAR for DMA-remapping specific code
1886e8a: x64, x2apic/intr-remap: code re-structuring, to be used by both DMA and Interrupt remapping
c42d9f3: x64, x2apic/intr-remap: fix the need for sequential array allocation of iommus
e61d98d: x64, x2apic/intr-remap: Intel vt-d, IOMMU code reorganization

Jesse, do you have any objections to this approach?
