Subject: [Qemu-devel] [PATCH 3/5] user-exec: Delete now-unused hppa and m68k cpu_signal_handler() code
Date: Tue, 14 Jun 2016 10:52:05 +0100	[thread overview]
Message-ID: <1465897927-4719-4-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1465897927-4719-1-git-send-email-peter.maydell@linaro.org>

Now that configure blocks attempts to build user-mode code on hppa
and m68k hosts, we can delete the cpu_signal_handler() implementations
for those architectures.
