[Qemu-arm] [PATCH v3 3/7] target/arm64: kvm debug set target_el when pas


From: Alex Bennée
Subject: [Qemu-arm] [PATCH v3 3/7] target/arm64: kvm debug set target_el when passing exception to guest
Date: Fri, 9 Nov 2018 15:21:15 +0000

When we are debugging the guest all exceptions come our way but might
be for the guest's own debug exceptions. We use the ->do_interrupt()
infrastructure to inject the exception into the guest. However, we are
missing a full setup of the exception structure, causing an assert
later down the line.
