if it's genuine fixes we can do it post-rc1, but it looks a tad wide 
for that:

 arch/x86/kernel/pci-swiotlb.c |    2 +-
 include/linux/swiotlb.h       |    3 +-
 lib/swiotlb.c                 |  115 ++++++++++++++++++++++-------------------

the patches came right in the merge window - that's too late for 
IOMMU bits, the patch cutoff is generally the beginning of the merge 
window. (Which was on March 23 in this window)

But i can queue them up in the .31 queue if it has all the Acks from 
you folks. Becky, mind resending the latest version, with all the 
acks in place?

Thanks,

	Ingo
