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/compiler.h:257,
from arch/arm/kernel/asm-offsets.c:10:
include/linux/kasan-checks.h:14:15: error: unknown type name 'bool'
static inline bool __kasan_check_read(const volatile void *p, unsigned int size)
^~~~
include/linux/kasan-checks.h:18:15: error: unknown type name 'bool'
static inline bool __kasan_check_write(const volatile void *p, unsigned int size)
^~~~
include/linux/kasan-checks.h:38:15: error: unknown type name 'bool'
static inline bool kasan_check_read(const volatile void *p, unsigned int size)
^~~~
include/linux/kasan-checks.h:42:15: error: unknown type name 'bool'
static inline bool kasan_check_write(const volatile void *p, unsigned int size)
^~~~

Caused by commit

4bb170e54bbd ("mm/kasan: change kasan_check_{read,write} to return boolean")

I have added the following patch for today:
