From 3ce465e04bfd8de9956d515d6e9587faac3375dc Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 10 Feb 2015 10:02:59 +0000 Subject: MIPS: Export FP functions used by lose_fpu(1) for KVM 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!
