The code and comment disagreed: the comment claimed that r6...r31
were copied, and consequently the arrays for "src" and "dst" were
declared with 26 entries, but the actual code ("lmw r5,0(r3)" and
"stmw r5,0(r4)") copied _27_ words (r5 through r31), which resulted
in false "POST cpu Error at multi test" messages.Fix the comment and the array sizes.
