Update CPU overrides for the DEC port with the recent additions, shaving off some effectively dead code: text data bss dec hex filename 5586952 233132 5990368 11810452 b43694 vmlinux.32-old 5581248 233140 5990368 11804756 b42054 vmlinux.32-new text data bss dec hex filename 6036936 356648 10756544 17150128 105b0b0 vmlinux.64-old 6029896 360752 10756544 17147192 105a538 vmlinux.64-new The data size increase is due to the special alignment requirement of `init_thread_union' aka `.data..init_task' moving it up to the nearest page boundary and making the amount of padding at its front rely on how far within a page text ends.
