[PATCH 00/10 v2] iommu/amd: lock splitting & GFP_KERNEL allocation

From: Sebastian Andrzej Siewior

The goal here is to make the memory allocation in get_irq_table() not
with disabled interrupts and having as little raw_spin_lock as possible
while having them if the caller is also holding one (like desc->lock
during IRQ-affinity changes).
I reverted one patch one patch in the iommu while rebasing since it
make job easier.

The patches were boot tested on an AMD EPYC 7601.
