Subject: [RFC v5 8/8] PCI: hv: Turn on the host bridge probing on ARM64
Date: Tue, 20 Jul 2021 21:44:29 +0800	[thread overview]
Message-ID: <20210720134429.511541-9-boqun.feng@gmail.com> (raw)
In-Reply-To: <20210720134429.511541-1-boqun.feng@gmail.com>

Now we have everything we need, just provide a proper sysdata type for
the bus to use on ARM64 and everything else works.
