Subjectlinux-next: build failure after merge of the printk tree
Hi Petr,

After merging the printk tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from include/linux/ftrace.h:11:0,
from include/linux/perf_event.h:48,
from include/linux/trace_events.h:10,
from include/trace/syscall.h:7,
from include/linux/syscalls.h:82,
from init/do_mounts.h:5,
from init/do_mounts_initrd.c:22:
include/linux/kallsyms.h: In function 'dereference_symbol_descriptor':
include/linux/kallsyms.h:63:8: error: implicit declaration of function '__module_address' [-Werror=implicit-function-declaration]
mod = __module_address((unsigned long)ptr);
^
include/linux/kallsyms.h:67:9: error: implicit declaration of function 'dereference_module_function_descriptor' [-Werror=implicit-function-declaration]
ptr = dereference_module_function_descriptor(mod, ptr);
^

and many more ...

Caused by commit

78675fe41d57 ("symbol lookup: introduce dereference_symbol_descriptor()")

I have used the printk tree from next-20171206 (with its version of the
above patch reverted due to yesterday's error) for today.

Stephen Rothwell
