Presumably another include needed:

arch/s390/lib/test_unwind.c:49:2: error: implicit declaration of function 'kmalloc' [-Werror=implicit-function-declaration]
arch/s390/lib/test_unwind.c:99:2: error: implicit declaration of function 'kfree' [-Werror=implicit-function-declaration]  

Hi Stephen:

It's not clear how this file manages to include linux/uio.h but

arch/s390/lib/test_unwind.c
arch/s390/include/asm/unwind.h
include/linux/ftrace.h
include/linux/kallsyms.h
include/linux/module.h
include/linux/elf.h
arch/s390/include/asm/elf.h
include/linux/compat.h
include/linux/socket.h
include/linux/uio.h

:-(
