Subject: [RFC PATCH 4/8] powerpc: add CPU field to struct thread_info

From: Ard Biesheuvel <[email-masked]>
Date: Tue, 14 Sep 2021 14:10:32 +0200

The CPU field will be moved back into thread_info even when
THREAD_INFO_IN_TASK is enabled, so add it back to powerpc's definition
of struct thread_info.
