Subject: [PATCH v3 3/7] accel/xen: Incorporate xen-mapcache.c
Date: Mon,  1 Feb 2021 12:29:01 +0100	[thread overview]
Message-ID: <20210201112905.545144-4-f4bug@amsat.org> (raw)
In-Reply-To: <20210201112905.545144-1-f4bug@amsat.org>

xen-mapcache.c contains accelerator related routines,
not particular to the X86 HVM machine. Move this file
to accel/xen/ (adapting the buildsys machinery).
