4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jingoo Han <jingoohan1@xxxxxxxxx> commit 294240ffe784e951dc2ef070da04fa31ef6db3a0 upstream. When kzalloc() is called under spin_lock(), GFP_ATOMIC should be used to avoid sleeping allocation. The call tree is: of_pci_range_to_resource() --> pci_register_io_range() <-- takes spin_lock(&io_range_lock); --> kzalloc() Signed-off-by: Jingoo Han <jingoohan1@xxxxxxxxx> Signed-off-by: Rob Herring <robh@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/of/address.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/of/address.c +++ b/drivers/of/address.c @@ -712,7 +712,7 @@ int __weak pci_register_io_range(phys_ad } /* add the range to the list */ - range = kzalloc(sizeof(*range), GFP_KERNEL); + range = kzalloc(sizeof(*range), GFP_ATOMIC); if (!range) { err = -ENOMEM; goto end_register; -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
