Jan,

I found an issue when booting the hypervisor after the patch with 
assertion at the line 64 of iommu_intr.c (in function get_intremap_entry).

Stack dump:
...........
get_intremap_entry+0x39/0x58
amd_iommu_read_msi_from_ire+0x74/0xac
iommu_read_msi_from_ire+0x3c/0x3f
set_msi_affinity+0x161/0x1ae
enable_iommu+0x681/0x7d2
amd_iommu_init+0x50b/0x6b1
amd_iov_detect+0x69/0xad
iommu_setup+0x67/0x171
__start_xen+0x278c/0x2b9d

************************************
Panic on CPU 0:
Assertion '(table != NULL) && (offset < INTREMAP_ENTRIES)' failed at 
iommu_intr.c:64

*************************************

Investigation showing table is not null and offset = 0.
