Subject: linux-next: build failure after merge of the powerpc tree
Date: Fri, 10 Feb 2023 14:38:29 +1100 [thread overview]
Message-ID: <20230210143829.4ab676bd@canb.auug.org.au> (raw)

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.
