Subject: linux-next: build warning after merge of the akpm-current tree

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/scsi/ipr.c: In function 'ipr_show_device_id':
drivers/scsi/ipr.c:4462:34: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'long unsigned int' [-Wformat=]
   len = snprintf(buf, PAGE_SIZE, "0x%llx\n", be64_to_cpu(res->dev_id));
                                  ^

Lots and lots like this :-(

Probably introduced by commit

  eef17fb79096 ("byteswap: try to avoid __builtin_constant_p gcc bug")

I guess __builtin_bswap64() has type "unsigned long int" :-(

Cheers,
