[Qemu-devel] [PULL 08/16] target/arm64: kvm debug set target_el when passing exception to guest

[Peter Maydell]

From: Alex Bennée <address@hidden>

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.
