    Subject[RFC patch 9/9] Stringify support commas
    #define MYDEF a, b, c

    __stringify(MYDEF) should be replaced by "a, b, c", but compilation fails
    because the __stringify macro expects only one argument. Fix it by using
    variable macro arguments in __stringify and __stringify_1.

    Needed in my current NMI safe iret paravirt support work so I can expand
    a macro containing assembly code into a string.
