Just checked the kbuild robot error and it is happening in ARC git tree when
built for i386 arch and the problem is independent from my patches. The build
error is the following:
drivers/pci/host/pcie-designware.c: In function 'dw_pcie_host_init':
>> drivers/pci/host/pcie-designware.c:556:7: error: implicit declaration of function
'pci_has_flag' [-Werror=implicit-function-declaration]
if (!pci_has_flag(PCI_PROBE_ONLY)) {
^
>> drivers/pci/host/pcie-designware.c:556:20: error: 'PCI_PROBE_ONLY' undeclared
(first use in
this function)
if (!pci_has_flag(PCI_PROBE_ONLY)) {
^
This problem has been already identified by Stephen Rothwell as you can see in
the following mailing list thread:
http://www.gossamer-threads.com/lists/linux/kernel/2341200
If there's something for me to do please let me know.
