Subject: linux-next: build failure after merge of the rcu tree

Hi Paul,

After merging the rcu tree, today's linux-next build (bfin
BF526-EZBRD_defconfig and several other bfin configs) failed like this:

In file included from include/linux/srcu.h:60:0,
                 from include/linux/notifier.h:15,
                 from include/linux/memory_hotplug.h:6,
                 from include/linux/mmzone.h:777,
                 from include/linux/gfp.h:5,
                 from include/linux/kmod.h:22,
                 from include/linux/module.h:13,
                 from include/linux/moduleloader.h:5,
                 from arch/blackfin/kernel/module.c:9:
include/linux/srcutiny.h: In function 'srcu_torture_stats_print':
include/linux/srcutiny.h:96:2: error: 'mod' undeclared (first use in this function)

Caused by commit

  54ffb22bd841 ("rcutorture: Move SRCU status printing to SRCU implementations")

arch/blackfin/kernel/module.c includes this:

#define pr_fmt(fmt) "module %s: " fmt, mod->name

added by commit

  b75a9e6bfba5 ("Blackfin: use more standard pr_fmt in the module loader")

before v2.6.39-rc2 ...
