Correct, they were not intended for immediate upstream merging, they 
werent even in auto-x86-next so there was no meaningful linux-next 
exposure.

I was surprised they went upstream via the PCI tree yesterday, just 
hours after i sent them over to Jesse and about an hour before -rc1 was 
released. [ Nor did intend the core/generic-dma-coherent bits to go 
upstream right before -rc1 - although those seem to be problem-free so 
far. ]

I stopped sending non-urgent patches to Linus days ago, to let things 
calm down for a smooth -rc1 release.
