Hi Andrew,

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

In file included from /home/sfr/next/next/tools/include/linux/list.h:5:0,
                 from arch/../util/map.h:6,
                 from arch/../util/event.h:8,
                 from arch/../util/debug.h:7,
                 from arch/common.c:4:
/home/sfr/next/next/tools/include/linux/../../../include/linux/list.h: In function 'list_force_poison':
/home/sfr/next/next/tools/include/linux/../../../include/linux/list.h:123:56: error: unused parameter 'entry' [-Werror=unused-parameter]
 static inline void list_force_poison(struct list_head *entry)
                                                        ^

and many more like that.

Caused by commit

  a471eb786598 ("mm, dax, pmem: introduce {get|put}_dev_pagemap() for dax-gup")

I just left the perf build broken for today.
