====================
net/iucv: updates 2021-08-09

Please apply the following iucv patches to netdev's net-next tree.

Remove the usage of register asm statements and replace deprecated
CPU-hotplug functions with the current version.
Use use consume_skb() instead of kfree_skb() to avoid flooding
dropwatch with false-positives, and 2 patches with cleanups.
