    LinuxKPI: add default_gfp()
    
    Various new allocation macros can take an optional gfp_t argument.
    If the argument is not given we need to set the GFP_KERNEL default.
    While this is only internally used and I initialy called it differently,
    should this spread elsewhere having the same name as in Linux will be
    good.
