Date: Mon, 17 Oct 2011 23:10:58 +0300	[thread overview]
Message-ID: <20111017201058.GA13916@elgon.mountain> (raw)

Hi,

The linux-next patch 54be566317b6 "gpio-ml-ioh: Support interrupt
function" generates a Sparse warning.

+               irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j],
+                                          GFP_KERNEL);
                                           ^^^^^^^^^^

The last argument should be a NUMA node, not a GFP_ flag.  I'm not
sure what the right fix is.  There are currently 5 callers in my
cscope for this function in linux-next.

2 pass GFP_KERNEL which is wrong.
2 pass 0 which maybe should be cpu_to_node(0)?
1 passes -1 which maybe could be NUMA_NO_NODE?

I'm probably embarrassing myself with my ignorance here, but I do
know that GFP_KERNEL isn't right.

regards,
dan carpenter
