Arnd Bergmann ae1f8d793a ARM: 9304/1: add prototype for function called only from asm 
When building with 'make W=1', the compiler warns about any function
definition that does not come with a prototype in a header, to ensure
it matches what the caller expects.

This includes functions that are only ever caller from assembly
code and don't technically need a declaration:

arch/arm/kernel/ftrace.c:227:6: error: no previous prototype for 'prepare_ftrace_return'
arch/arm/kernel/ptrace.c:850:16: error: no previous prototype for 'syscall_trace_enter'

arch/arm/mm/proc-v7-bugs.c:293:6: error: no previous prototype for 'cpu_v7_bugs_init'

arch/arm/vfp/vfpmodule.c:323:6: error: no previous prototype for 'VFP_bounce'

Add the prototypes anyway, to allow enabling this warning by default in
the future.
