We have different CPER error type. For example, for processor error type,
it has following definition:

struct cper_sec_proc_generic {
        __u64   validation_bits;
        __u8    proc_type;
        __u8    proc_isa;
        __u8    proc_error_type;
        __u8    operation;
        __u8    flags;
        __u8    level;
        __u16   reserved;
        __u64   cpu_version;
        char    cpu_brand[128];
        __u64   proc_id;
        __u64   target_addr;
        __u64   requestor_id;
        __u64   responder_id;
        __u64   ip;
};

If we want to show it in string format, 256 bytes should be not enough. But
by now we don't use this macro for processor error type so I will shrink it
to 256 bytes and add a comment for it.
