    kisskb build service reported ARC defconfig build failures in linux-next
    
    | arch/arc/include/asm/mmu.h:75:21: error: 'NR_CPUS' undeclared here (not in a function)
    | make[3]: *** [arch/arc/mm/ioremap.o] Error 1
    | make[2]: *** [arch/arc/mm] Error 2
    | make[1]: *** [arch/arc] Error 2
    
    which I bisected to a subtle side-effect of a totally benign mm patch
    ("mm, vmalloc: properly track vmalloc users") which caused a header
    include chain deviation - asm/mmu.h using NR_CPUS before including
    linux/threads.h
    
    Fix that by adding the dependnet header and while it at fix a related
    header to include linux headers aheads of asm headers as sometimes that
    slso triggers such issues !
