Subject: linux-next: rr tree build failure

Hi Rusty,

Today's linux-next build (x86_64 allmodconfig) failed like this:

arch/x86/kernel/cpu/cpufreq/powernow-k8.c: In function 'powernowk8_target':
arch/x86/kernel/cpu/cpufreq/powernow-k8.c:1139: error: implicit declaration of function 'tsk_cpumask'
arch/x86/kernel/cpu/cpufreq/powernow-k8.c:1139: warning: passing argument 2 of 'cpumask_copy' makes pointer from integer without a cast
include/linux/cpumask.h:466: note: expected 'const struct cpumask *' but argument is of type 'int'

Caused by commit 9dd4c5ab546fcac98cfb9ca24ed5cc1bf7f08334
("cpumask:tsk_cpus_allowed-not-tsk_cpumask") from the rr tree interacting
with commit b8cbe7e82ec8b55d7bbdde66fc69e788fde00dc6 ("[CPUFREQ] cpumask:
don't put a cpumask on the stack in x86...cpufreq/powernow-k8.c") from
the cpufreq tree.

I have applied this merge fix up patch and can carry it as necessary:
