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

Hi all,

After merging the origin tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/asm-generic/percpu.h:7,
                 from arch/x86/include/asm/percpu.h:556,
                 from arch/x86/include/asm/preempt.h:6,
                 from include/linux/preempt.h:78,
                 from include/linux/spinlock.h:51,
                 from include/linux/seqlock.h:36,
                 from include/linux/time.h:6,
                 from include/linux/stat.h:19,
                 from include/linux/module.h:13,
                 from arch/x86/crypto/glue_helper.c:13:
include/linux/random.h:123:24: error: variable 'net_rand_state' with 'latent_entropy' attribute must not be local
  123 | DECLARE_PER_CPU(struct rnd_state, net_rand_state) __latent_entropy;
      |                        ^~~~~~~~~
include/linux/percpu-defs.h:88:38: note: in definition of macro 'DECLARE_PER_CPU_SECTION'
   88 |  extern __PCPU_ATTRS(sec) __typeof__(type) name
      |                                      ^~~~

  123 | DECLARE_PER_CPU(struct rnd_state, net_rand_state) __latent_entropy;
      | ^~~~~~~~~~~~~~~

Caused by commit

  f227e3ec3b5c ("random32: update the net random state on interrupt and activity")

I have reverted that commit for today.

In case it matters:

$ x86_64-linux-gnu-gcc --version
x86_64-linux-gnu-gcc (Debian 9.3.0-13) 9.3.0

Cheers,
