Subject: mn10300: fix build error of missing fpu_save()
From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
[ Upstream commit 3705ccfdd1e8b539225ce20e3925a945cc788d67 ]
When CONFIG_FPU is not enabled on arch/mn10300, <asm/switch_to.h> 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 <asm/fpu.h> in <asm/switch_to.h> so that an empty
static inline fpu_save() is defined.
