Subject: [PATCH v3 3/4] libs/foreignmemory: Use XEN_PAGE_* definitions
Date: Mon, 23 Aug 2021 20:02:55 +0300	[thread overview]
Message-ID: <b67bbe5e4a54e28c1d63cd1144081b779b9a6a8d.1629737453.git.costin.lupu@cs.pub.ro> (raw)
In-Reply-To: <cover.1629737453.git.costin.lupu@cs.pub.ro>

These changes refine the changes in 0dbb4be7 which added a dependency to
xenctrl library. We use the XEN_PAGE_* definitions instead of the XC_PAGE_*
definitions and therefore we get rid of the unnecessary dependency.
