[PATCH v6 08/25] target/hppa: call plugin trap callbacks

Posted by Julian Ganz 1 day, 18 hours ago

We identified a number of exceptions as interrupts, and we assume any
unknown exception is also an interrupt. HPPA appears to not have any
form of host-call.

This change places the hook for PA-RISC targets.
