The changes in that branch above have now landed in Linus' tree with:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=557acb3d2cd9c82de19f944f6cc967a347735385

It would be good if we could get both patches applied via the same tree
or within the same cycle to avoid having either PCIe or SATA broken on
these platforms.

Thanks!
