Subject: [PATCH v16 12/21] powerpc: Use sizeof(struct thread_info) in INIT_SP_LIMIT
Date: Tue,  5 Feb 2019 22:32:10 +1100	[thread overview]
Message-ID: <20190205113219.17903-13-mpe@ellerman.id.au> (raw)
In-Reply-To: <20190205113219.17903-1-mpe@ellerman.id.au>

From: Christophe Leroy <christophe.leroy@c-s.fr>

Currently INIT_SP_LIMIT uses sizeof(init_thread_info), but that symbol
won't exist when we enable THREAD_INFO_IN_TASK. So just use the sizeof
the type which is the same value but will continue to work.
