Hi Bjorn, After merging the pci tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: ERROR: ".pci_try_set_mwi" [drivers/scsi/qla2xxx/qla2xxx.ko] undefined! ERROR: ".pci_clear_mwi" [drivers/scsi/qla2xxx/qla2xxx.ko] undefined! ERROR: ".pci_try_set_mwi" [drivers/scsi/lpfc/lpfc.ko] undefined! Caused by commit 9259d755975f ("PCI: Move EXPORT_SYMBOL so it immediately follows function/variable"). arch/powerpc/include/asm/pci.h defines PCI_DISABLE_MWI and there are two version of those functions depending on the setting of that symbol. I have used the pci tree from next-20140610 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
