The first two patches are functionally independent, and they're presented
here merely in the order I came to notice the respective issues. At least
patch 2 wants seriously considering for 4.20.
While alternatives were considered for patch 2, it's left as it was in v1
for now. The disposition there depends on (a) the four new patches, in
particular what the last patch does and (b) backporting considerations
(we probably don't want to backport any of the radix tree tidying).
1: AMD/IOMMU: drop stray MSI enabling
2: x86/PCI: init segments earlier
3: radix-tree: purge node allocation override hooks
4: radix-tree: drop "root" parameters from radix_tree_node_{alloc,free}()
5: radix-tree: introduce RADIX_TREE{,_INIT}()
6: PCI: drop pci_segments_init()
