Re-submission of regular Leap 42.3 kernel update.
The regression of multipath was addressed now.

(bnc#1065600).

- blacklist.conf: Add 9494ea90a56d Revert "iommu/amd: Suppress IO_PAGE_FAULTs in kdump kernel"
This patch is part of a patch-set which we are not going to
backport completly. And without the other patches this
revert doesn't make sense.

Only removes a feature not supported by Intel. Not a real
bug fix.
