The struct pci_dev is too large to allocate on the stack. This patch removes the fake pci device in early config access and instead uses the pci bus to get the same functionality. Signed-off-by: Keith Busch <keith.busch@xxxxxxxxx> Cc: Atsushi Nemoto <anemo@xxxxxxxxxxxxx> Cc: Ralf Baechle <ralf@xxxxxxxxxxxxxx> --- Got the 'ok' (link below), but I don't see this is merged yet. That's okay, since I need to include it in this series to avoid 0'day build failure. If this is ok with everyone, perhaps this can go through 'pci'. https://www.linux-mips.org/archives/linux-mips/2016-09/msg00255.html arch/mips/txx9/generic/pci.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/arch/mips/txx9/generic/pci.c b/arch/mips/txx9/generic/pci.c index 1f6bc9a..285d84e 100644 --- a/arch/mips/txx9/generic/pci.c +++ b/arch/mips/txx9/generic/pci.c @@ -29,12 +29,8 @@ static int __init early_read_config_word(struct pci_controller *hose, int top_bus, int bus, int devfn, int offset, u16 *value) { - struct pci_dev fake_dev; struct pci_bus fake_bus; - fake_dev.bus = &fake_bus; - fake_dev.sysdata = hose; - fake_dev.devfn = devfn; fake_bus.number = bus; fake_bus.sysdata = hose; fake_bus.ops = hose->pci_ops; @@ -45,7 +41,7 @@ early_read_config_word(struct pci_controller *hose, else fake_bus.parent = NULL; - return pci_read_config_word(&fake_dev, offset, value); + return pci_bus_read_config_word(&fake_bus, devfn, offset, value); } int __init txx9_pci66_check(struct pci_controller *hose, int top_bus, -- 2.7.2 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
