Hold on, CA57 and CA53 are ARMv8 cores. So are you using 32-bit or 64-bit 
guests?
64-bit guests.

64-bit guest should not have any Set/Way operations unless you are using a very 
very old Linux. So what is the version of each guest?
All of them derived from 4.14.35.

There should be no Set/Way in Linux 4.14. So I am a bit confused how can even 
reach this code.

Can you look if there are a Set/Way executed in Linux? And where? You can add 
some code in arm64/vsysreg.c to track that down.
Yep, I'm still looking into details of that stuff.
Yet this patch makes the system functional.
