Subject: [linux-next][PATCH] cpumask:cpumask_of_node-ia64 fix

===
Subject: [PATCH] cpumask:cpumask_of_node-ia64 fix
Impact: bug fix

commit 07c636deede53ff3e96d54df0ece2c838e61951f introduce new CPU mask API and change cpu_mask variable type.

-----------------------------------------------
-               cpumask_t cpu_mask;
+               const struct cpumask *cpu_mask;
--------------------------------------------------


However, its change is incomplete. in build time, compiler output following type mismatch warnings.

  arch/ia64/kernel/iosapic.c:708: warning: passing argument 2 of '__cpu_clear' from incompatible pointer type
  arch/ia64/kernel/iosapic.c:711: warning: passing argument 1 of '__cpus_weight' from incompatible pointer type
  arch/ia64/kernel/iosapic.c:719: warning: passing argument 1 of '__first_cpu' from incompatible pointer type
  arch/ia64/kernel/iosapic.c:720: warning: passing argument 2 of '__next_cpu' from incompatible pointer type
