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

Hi all,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

In file included from include/linux/rcupdate.h:28,
                 from include/linux/rculist.h:11,
                 from include/linux/pid.h:5,
                 from include/linux/sched.h:14,
                 from arch/arm/kernel/asm-offsets.c:11:
include/linux/bottom_half.h: In function 'local_bh_disable':
include/linux/bottom_half.h:19:24: error: '_THIS_IP_' undeclared (first use in this function)
   19 |  __local_bh_disable_ip(_THIS_IP_, SOFTIRQ_DISABLE_OFFSET);
      |                        ^~~~~~~~~
include/linux/bottom_half.h:19:24: note: each undeclared identifier is reported only once for each function it appears in
include/linux/bottom_half.h: In function 'local_bh_enable':

   32 |  __local_bh_enable_ip(_THIS_IP_, SOFTIRQ_DISABLE_OFFSET);
      |                       ^~~~~~~~~

Presumably caused by a commit in the series that starts with

  dcaf7a5f413b ("kernel.h: drop unneeded <linux/kernel.h> inclusion from other headers")

I have applied the following patch for today (though there may be a
better solution).

Subject: [PATCH] bottom_half.h needs kernel.h

for _THIS_IP_ on arm at least
