Subject: [PATCH v2 13/17] x86/xen: enable Hygon support to Xen
Date: Mon, 23 Jul 2018 21:20:33 +0800	[thread overview]
Message-ID: <1532352037-7151-14-git-send-email-puwen@hygon.cn> (raw)
In-Reply-To: <1532352037-7151-1-git-send-email-puwen@hygon.cn>

To make Xen work correctly on Hygon platforms, reuse AMD's Xen support
code path and add vendor check for Hygon along with AMD.
