The load_up_fpu and load_up_altivec functions were never intended to be called from C, and do things like modifying the MSR value in their callers' stack frames, which are assumed to be interrupt frames. In addition, on 32-bit Book S they require the MMU to be off. This makes KVM use the new load_fp_state() and load_vr_state() functions instead of load_up_fpu/altivec. This means we can remove the assembler glue in book3s_rmhandlers.S, and potentially fixes a bug on Book E, where load_up_fpu was called directly from C.
