Subject: [PATCH 0/2] Quirk Intel PCH root ports for ACS-like features

As described in 2/2 many Intel root ports lack PCIe ACS capabilities
which results in excessively large IOMMU groups.  Many of these root
ports do provide isolation capabilities, we just need to use device
specific mechanisms to enable and verify.  Long term, I hope we can
round out this list (particularly to include X79 root ports) and
more importantly, encourage proper PCIe ACS support in future
products.  I'm really hoping we can get this in during the 3.14 cycle.
Thanks,

Alex
