    Subject[bug #2] Re: [PATCH 00/35] cpumask: Replace cpumask_t with struct cpumask

    Thomas has started a -tip cross-build test, and there's massive
    cross-build failures as well due to the cpumask changes:

    Run 140: 11 of 19 OK

    8 architecture configs out of 19 fail to build, 7 of which failures is
    this patchset's fault:

    powerpc, ps3_defconfig:

    error: implicit declaration of function '__cpus_setall'

    m32r defconfig:

    from /home/tglx/work/kernel/autoqa/linux-2.6-tip/arch/m32r/kernel/smp.c:18:
    include2/asm/smp.h:66: error: expected ')' before '*' token
    include2/asm/smp.h:66: error: expected ')' before 'cpu_possible_mask'
    include2/asm/smp.h:67: error: expected ')' before '*' token
    include2/asm/smp.h:67: error: expected ')' before 'cpu_present_mask'

    xtensa defconfig:

    from /home/tglx/work/kernel/autoqa/linux-2.6-tip/arch/xtensa/k
    'CONFIG_NR_CPUS' undeclared here (not in a function)

    powerpc mpc5200_defconfig:

    warning: "CONFIG_NR_CPUS" is not defined
    make[2]: *** [arch/powerpc/kernel/asm-offsets.s] Error 1
    make[1]: *** [prepare0] Error 2

    sparc32 defconfig:

    error: 'CONFIG_NR_CPUS' undeclared here (not in a function)

    powerpc ppc64_defconfig:

    e.c:117: error: implicit declaration of function '__cpus_setall'
    make[3]: *** [arch/powerpc/platforms/cell/spu_base.o] Error 1

    s390 defconfig:

    /home/tglx/work/kernel/autoqa/linux-2.6-tip/arch/s390/kernel/smp.c: In
    function '__smp_call_function_map':
    error: request for member 'bits' in something not a structure or union

    it seems to me that this commit is massively borked:

    4a792c2: cpumask: make CONFIG_NR_CPUS always valid

    but some of the others seems to be suspect as well - there's at least 3
    different failure patterns.
