Currently there are a few source file in the kernel can't parse property due to over run of the concatenation buffer. They either have a large string concatnation or huge macro expand. The TRACE macro is a common one. Now show_token_sequence and quote_token_sequence is combined into one function with a bigger buffer. It works for most of the kernel source except the config_data.h. The kernel config is about 70K, larger than the string allocator chunk size. It needs some plumbing work in the allocator before we can allow bigger string token.
