Subject: [RFC v4 5/7] PCI: hv: Use pci_host_bridge::domain_nr for PCI domain
Date: Wed, 14 Jul 2021 18:27:35 +0800 [thread overview]
Message-ID: <20210714102737.198432-6-boqun.feng@gmail.com> (raw)
In-Reply-To: <20210714102737.198432-1-boqun.feng@gmail.com>
No functional change, just store and maintain the PCI domain number in
the generic pci_host_bridge instead of x86 specific pci_sysdata.
