Merge tag 'iommu-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull iommu fix from Will Deacon:
"Fix interrupt table length definition for AMD IOMMU.
It's actually a fix for a fix, where the size of the interrupt
remapping table was increased but a related constant for the
size of the interrupt table was forgotten"
* tag 'iommu-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
iommu/amd: Set DTE[IntTabLen] to represent 512 IRTEs
