Subject: [PATCH for-6.2 1/8] softmmu: Use accel_find("xen") instead of xen_available()
Date: Fri, 30 Jul 2021 11:59:40 +0100	[thread overview]
Message-ID: <20210730105947.28215-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210730105947.28215-1-peter.maydell@linaro.org>

The xen_available() function is used only to produce an error
for some Xen-specific command line options in QEMU binaries where
Xen support was not compiled in: it just returns the value of
the CONFIG_XEN define.

Now that accelerators are QOM classes, we can check for
"does this binary have Xen compiled in" with accel_find("xen"),
and drop the xen_available() function.
