* Russell King - ARM Linux <linux@armlinux•org.uk> [180525 07:02]:
> Third version:
> - Remove "PSCI" from the SMC version of the workaround as well.
> - Avoid reporting active workaround if the IBE bit is not set.
> - Only probe for workaround_1 on Cortex A57 and A72, or non-ARM CPUs.
> - Require features probe for workaround_1 to return zero.
> - Validation that all CPUs in the system have the same workaround status.
> - Avoid corrupting r12 in workaround_1 KVM hypervisor implementation.

want to count that as Tested-by though :) But feel free to add:
