Subject: [PATCH v2 36/49] PCI: Only treat non-pef mmio64 as pref if host-bridge has_mem64
Date: Tue, 14 Jul 2015 15:47:07 -0700 [thread overview]
Message-ID: <1436914040-13206-37-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1436914040-13206-1-git-send-email-yinghai@kernel.org>
If host bridge does not have mmio64 above 4G, We don't need to
treat device non-pref mmio64 as as pref mmio64.
