Hi all,

After merging the powerpc tree, today's linux-next build (powerpc64
allnoconfig) failed like this:

arch/powerpc/kernel/setup_64.c: In function 'early_setup':
arch/powerpc/kernel/setup_64.c:400:34: error: 'struct thread_info' has no member named 'cpu'
400 | task_thread_info(current)->cpu = boot_cpuid; // fix task_cpu(current)
| ^~

Caused by commit

0ecf51ca51e5 ("powerpc/64: Fix task_cpu in early boot when booting non-zero cpuid")

# CONFIG_SMP is not set

I applied the following fix up for today.
