Hello Michael, In the case of no sibling call within the livepatch then the store is only "restoring" the r2 value that was already there as it is stored and retrieved from the livepatch stack. The only time that the r2 value is corrupted is in the case of a sibling call and thus this additional store is just restoring the caller's context as a safety precaution. Also should this explanation be put into the patch itself or will these messages suffice as a reference?
Cheers, Ryan
