v2->v3:
- split the error-logging function to a separate patch (Andrii)
- make the error buffers smaller (Andrii)
- include size of memory region for PTR_TO_MEM (Andrii)
- nits from Andrii and Eduard

v1->v2:
- make the error message include more info about the context of the
  zero-sized access (Andrii)
