Subject: [PATCH v5 14/18] target/s390x: Rely on unwinding in s390_cpu_virt_mem_rw
Date: Tue,  1 Oct 2019 10:16:10 -0700	[thread overview]
Message-ID: <20191001171614.8405-15-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191001171614.8405-1-richard.henderson@linaro.org>

For TCG, we will always call s390_cpu_virt_mem_handle_exc,
which will go through the unwinder to set ILEN.  For KVM,
we do not go through do_program_interrupt, so this argument
is unused.
