Subject: [RFC v2 7/7] PCI: hv: Turn on the host bridge probing on ARM64
Date: Mon,  3 May 2021 22:46:35 +0800	[thread overview]
Message-ID: <20210503144635.2297386-8-boqun.feng@gmail.com> (raw)
In-Reply-To: <20210503144635.2297386-1-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.
