[FIX]
The following patches cherry-picked from linux-next fixes this issue.
5016bdb796b3 iommu/iova: Fix underflow bug in __alloc_and_insert_iova_range
d9a5f8adaec9 iommu/dma: Plumb in the per-CPU IOVA caches
fc7f6142bacb iommu/dma: Clean up MSI IOVA allocation
568c61384ea1 iommu/dma: Convert to address-based allocation
dddd632b072f iommu/dma: Implement PCI allocation optimisation
de84f5f049d9 iommu/dma: Stop getting dma_32bit_pfn wrong
[Test case]
After applying the patches the kernel boot with no soft lockups. This was
tested by me on Zesty 4.10.0-20.22 kernel on QDF2400 SDP.
[Regression Potential]
These patches applicable to iommu driver and does not impact any platform
code. Please see the comments section for regression tests on ARM64, Power8 and
intel platforms.
