+       show_reg_bits(m, "CR4", cr4_format, cr4);
 
Can %pXX formats use more than one argument?  If so, we might be able to move
all my code to lib/vsprintf.c and just write:

        seq_printf(m, "CR4: %pBITS: 0x%lx\n", cr4_format, cr4, cr4);

If they can't, we could bundle the format and value into a structure:

struct printbits {
        char *fmt;
        u64 val;
};

{
        struct printbits p;

        p.fmt = cr4_format;
        p.val = __read_cr4();
        seq_printf(m, "CR4: %pBITS: 0x%lx\n", &p, p.val);
}
