    KVM: PPC: Use load_fp/vr_state rather than load_up_fpu/altivec · 09548fda
    Paul Mackerras authored
    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.
