commit3ce465e04bupstream. Export the _save_fp asm function used by the lose_fpu(1) macro to GPL modules so that KVM can make use of it when it is built as a module. This fixes the following build error when CONFIG_KVM=m due to commitf798217dfd("KVM: MIPS: Don't leak FPU/DSP to guest"): ERROR: "_save_fp" [arch/mips/kvm/kvm.ko] undefined!
