<div class='commit-subject'>mn10300: fix build error of missing fpu_save()</div><div class='commit-msg'>When CONFIG_FPU is not enabled on arch/mn10300, &lt;asm/switch_to.h&gt; causes
a build error with a call to fpu_save():

  kernel/built-in.o: In function `.L410':
  core.c:(.sched.text+0x28a): undefined reference to `fpu_save'

Fix this by including &lt;asm/fpu.h&gt; in &lt;asm/switch_to.h&gt; so that an empty
static inline fpu_save() is defined.
