+Subject: MIPS: Export FP functions used by lose_fpu(1) for KVM
+
+From: James Hogan <james.hogan@imgtec.com>
+
+commit 3ce465e04bfd8de9956d515d6e9587faac3375dc upstream.
+
+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 commit
+f798217dfd03 ("KVM: MIPS: Don't leak FPU/DSP to guest"):
+
+ERROR: "_save_fp" [arch/mips/kvm/kvm.ko] undefined!
