Many of the core ARM kernel files are not modules, but just
including module.h for exporting symbols. Now these files can
use the lighter footprint export.h for this role.
There are probably lots more, but ARM files of mach-* and plat-*
don't get coverage via a simple yesconfig build. They will have
to be cleaned up and tested via using their respective configs.

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
As __builtin_return_address(n) doesn't work for ARM with n > 0, the
kernel needs its own implementation.
This fixes many warnings saying:
warning: unsupported argument to '__builtin_return_address'
The new methods and walk_stackframe must not be instrumented because
CALLER_ADDRESSx is used in the various tracers and tracing the tracer is
a bad idea.
What's currently missing is an implementation using unwind tables. This
is not fatal though, it's just that the tracers don't get enough
information to be really useful.
Note that if both ARM_UNWIND and FRAME_POINTER are enabled,
walk_stackframe uses unwind information. So in this case the same
implementation is used as when FRAME_POINTER is disabled.
