    Subject[PATCH] [2.6.24] Add PPC nvram ioctls to compat_ioctl
    Fix the following console warning when running 'nvsetenv', and makes
    setting of new variables work again:

    ioctl32(nvsetenv:4022): Unknown cmd fd(3) cmd(20007043){t:'p';sz:0}
    arg(00000003) on /dev/nvram

    That's the IOC_NVRAM_SYNC call.
