Hi, here is the second version of this patch-set. The first version with some more introductory text can be found here: https://lore.kernel.org/lkml/20200407183742.4344-1-joro@xxxxxxxxxx/ Changes v1->v2: * Rebased to v5.7-rc1 * Re-wrote the arm-smmu changes as suggested by Robin Murphy * Re-worked the Exynos patches to hopefully not break the driver anymore * Fixed a missing mutex_unlock() reported by Marek Szyprowski, thanks for that. There is also a git-branch available with these patches applied: https://git.kernel.org/pub/scm/linux/kernel/git/joro/linux.git/log/?h=iommu-probe-device-v2 Please review.

Hi Joerg, With this patchset, I have an epyc system where if I boot with iommu=nopt and force a dump I will see some io page faults for a nic on the system. The vmcore is harvested and the system reboots. I haven't reproduced it on other systems yet, but without the patchset I don't see the io page faults during the kdump. Regards, Jerry
