For preference I'd rather get something that can be applied to -next so that we can enable PIL loading on current kernels instead of waiting an indeterminate time for an iommu non-pixel resolution. i.e. we are better of with stuff that works now instead of gating ourselves forever on a fix that may be months or years off. --- bod the optimist
