Subject: [PATCH v5 02/14] x86/xen: use X86_SUBARCH_XEN for PV guest boots
Date: Fri, 8 Apr 2016 16:57:05 -0700 [thread overview]
Message-ID: <1460159825-13212-1-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1460158825-13117-1-git-send-email-mcgrof@kernel.org>
The use of subarch should have no current effect on Xen
PV guests, as such this should have no current functional
effects.
