Hi,

Revert the code that associates the group pointer with the S2CR as this
code causing an issue when the SMMU device has more than one master
device.

It is not clear to me why this change was first added. Are we missingany feature when reverting it?

This code is merged with the commit  "xen/arm: smmuv1: Intelligent
SMR allocation”.

This wants a fixes tag. Can be added on commit if there is nothing elseto change.


Cheers,
