So the difficulty of a-priori estimation of the second kernel's needs is removed and the first kernel obtains extra memory. - The 5 patch series "generalize panic_print's dump function to be used by other kernel parts" from Feng Tang implements some consolidation and rationalizatio of the various ways in which a faiing kernel splats information at the operator.
