Subject: [PATCH 13/16] ARM: vfp: add vfp_entry prototype

From: Arnd Bergmann <arnd@...db.de>

vfp_entry is only called from assembler code, so it does not
need a declaration. Since gcc complains when extra warnings
are enabled, add one anyway to avoid:

arch/arm/vfp/vfpmodule.c:657:17: warning: no previous prototype for function 'vfp_entry' [-Wmissing-prototypes]
