Subject: Re: [PATCH] iommu: intel: remove flooding of non-error logs, when
 new-DMA-PTE is the same as old-DMA-PTE.

The userspace process is qemu.

I compiled qemu from latest source, installed via "sudo make install"
on host-machine, rebooted the host-machine, and booted up the
guest-machine on the host-machine. Now, no kernel-flooding is seen on
the host-machine.

For me, the issue is thus closed-invalid; admins may take the
necessary action to officially mark ;)

Thanks and Regards,
