Subject: [PATCH] powerpc/pseries: add missing cpumask.h include file

References: bsc#1065729
Patch-mainline: v4.20-rc1
Git-commit: 8dce6b2215eaa91dbf04463e11098a48748da5ab

Build error is encountered when inlcuding <asm/rtas.h> if no explicit or
implicit include of cpumask.h exists in the including file.

In file included from arch/powerpc/platforms/pseries/hotplug-pci.c:3:0:
./arch/powerpc/include/asm/rtas.h:360:34: error: unknown type name 'cpumask_var_t'
 extern int rtas_online_cpus_mask(cpumask_var_t cpus);
                                  ^
./arch/powerpc/include/asm/rtas.h:361:35: error: unknown type name 'cpumask_var_t'
 extern int rtas_offline_cpus_mask(cpumask_var_t cpus);
