host_dmesg_with_stolen_memory_enabled

This message is gotten from host when I boot a guest drm-intel-nightly kernel
with stolen memory enabled, I saw gpu hang in guest and reproduced this issue.
>From this message we could see there are tons of IOMMU read/write fault at
0xdaxxxxx where are stolen memory. So igd are accessing stolen memory.
