Subject: [PATCH 3/4] powerpc: Don't include lppaca.h in paca.h
Date: Wed, 23 Aug 2023 15:53:16 +1000 [thread overview]
Message-ID: <20230823055317.751786-3-mpe@ellerman.id.au> (raw)
In-Reply-To: <20230823055317.751786-1-mpe@ellerman.id.au>
By adding a forward declaration for struct lppaca we can untangle paca.h
and lppaca.h. Also move get_lppaca() into lppaca.h for consistency.
Add includes of lppaca.h to some files that need it.
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
