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:

http://www.tglx.de/autoqa-cgi/index?run=140&tree=8

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:

/home/tglx/work/kernel/autoqa/linux-2.6-tip/arch/s390/kernel/smp.c: In

/home/tglx/work/kernel/autoqa/linux-2.6-tip/arch/s390/kernel/smp.c:120:
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.
