commit 8386207f37e98453e1de3f51e50eeeea089103f9 upstream.
An incorrect argument order calling amd_iommu_dev_flush_pasid_pages() causes improper flushing of the IOMMU, leaving the old value of GCR3 from a previous process attached to the same PASID.
The function has the signature:
void amd_iommu_dev_flush_pasid_pages(struct iommu_dev_data *dev_data, ioasid_t pasid, u64 address, size_t size)
Correct the argument order.
