Subject: linux-next: build failure after merge of the bitmap tree

Hi all,

After merging the bitmap tree, today's linux-next build (powerpc
allyesconfig) failed like this:

ld: arch/powerpc/kernel/head_64.o: in function `generic_secondary_common_init':
(.text+0x545e): undefined reference to `nr_cpu_ids'

Caused by commit

  c90c5bd9f2d6 ("lib/cpumask: add FORCE_NR_CPUS config option")

This build has CONFIG_FORCE_NR_CPUS set but the (assembler) code expects
nr_cpu_ids to be a variable ...

I have reverted that commit for today.
