Subject: [PATCH v2 4/7] powerpc: add CPU field to struct thread_info
Date: Thu, 30 Sep 2021 14:58:10 +0200	[thread overview]
Message-ID: <20210930125813.197418-5-ardb@kernel.org> (raw)
In-Reply-To: <20210930125813.197418-1-ardb@kernel.org>

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.
