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:

  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.
