This should fix it... (now in powerpc.git)

    powerpc: Export variables used in conversions to/from cputime_t
    
    The inline cputime_to_foo and foo_to_cputime conversion functions in
    include/asm-powerpc/cputime.h refer to 5 variables, which need to be
    exported if those functions are to be usable from modules.
