mm/z3fold.c: improve compression by extending search The current z3fold implementation only searches this CPU's page lists for a fitting page to put a new object into. This patch adds quick search for very well fitting pages (i. e. those having exactly the required number of free space) on other CPUs too, before allocating a new page for that object.
