microblaze: Do not use module.h in files which are not modules Based on the patch: "lib: reduce the use of module.h wherever possible" (sha1: 8bc3bcc93a2b4e47d5d410146f6546bca6171663) fix all microblaze files which are not modules. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

microblaze: ftrace: add static function tracer If -pg of gcc is enabled with CONFIG_FUNCTION_TRACER=y. a calling to _mcount will be inserted into each kernel function. so, there is a possibility to trace the kernel functions in _mcount. This patch add the specific _mcount support for static function tracing. by default, ftrace_trace_function is initialized as ftrace_stub(an empty function), so, the default _mcount will introduce very little overhead. after enabling ftrace in user-space, it will jump to a real tracing function and do static function tracing for us.
