The IOMMU interrupt handling in bottom half must clear the PPR log interrupt
and event log interrupt bits to re-enable the interrupt. This is done by
writing 1 to the memory mapped register to clear the bit. Due to hardware bug,

In the current interrupt handling scheme, there are as many threads as

the time of registering interrupt handlers (request_threaded_irq).
When an IOMMU HW generates
