[RFC v8 22/28] hw/arm/smmuv3: Fill the IOTLBEntry arch_id on NH_VA inval


From: Eric Auger
Subject: [RFC v8 22/28] hw/arm/smmuv3: Fill the IOTLBEntry arch_id on NH_VA invalidation
Date: Thu, 25 Feb 2021 11:52:27 +0100

When the guest invalidates one S1 entry, it passes the asid.
When propagating this invalidation downto the host, the asid
information also must be passed. So let's fill the arch_id field
introduced for that purpose and accordingly set the flags to
indicate its presence.
