Hello,
I noticed the following warnings while building the upstream kernel as of

The commit I checked out at was cac7f2429872d3 : Linux 3.18-rc2.
Please verify if any of these can be fixed.
a. lib/cpumask.c: In function ‘cpumask_set_cpu_local_first’:
lib/cpumask.c:194:25: warning: the address of ‘cpu_all_bits’ will always
