Subject: [RFC v3 7/7] PCI: hv: Turn on the host bridge probing on ARM64
Date: Thu, 10 Jun 2021 00:32:11 +0800 [thread overview]
Message-ID: <20210609163211.3467449-8-boqun.feng@gmail.com> (raw)
In-Reply-To: <20210609163211.3467449-1-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.
