Oh - one more thing - and my apologies for not spotting this before:

dst = allocate_buf_for_compression(big_buf_sz);

No - you may not call kmalloc() in oops/panic context. Please pre-allocate
everything you need in some initialization code to make sure that we don't
fail in the panic path because we can't get the memory we need.
