Subject: [PCI] BUG: unable to handle kernel paging request at fffffffffffffff8
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/YijingWang/linux-pci.git enumer11
commit 3e13c9fbd94599113876de94efbae2b36ea8f335
Author: Yijing Wang <wangyijing@...wei.com>
AuthorDate: Tue Apr 28 11:52:30 2015 +0800
Commit: Yijing Wang <wangyijing@...wei.com>
CommitDate: Tue Apr 28 12:32:26 2015 +0800
PCI: Remove platform specific pci_domain_nr()
Now pci_host_bridge holds the domain number,
so we could eliminate all platform specific
pci_domain_nr().
