Subject: [PATCH 9/20] powerpc/mm: Call mmu_context_init() from ppc64 (v2)
Date: Fri, 24 Jul 2009 19:15:26 +1000 [thread overview]
Message-ID: <20090724091539.AD25FDDD1B@ozlabs.org> (raw)
In-Reply-To: <1248426902.401617.944220131651.qpush@grosgo>
Our 64-bit hash context handling has no init function, but 64-bit Book3E
will use the common mmu_context_nohash.c code which does, so define an
empty inline mmu_context_init() for 64-bit server and call it from
our 64-bit setup_arch()

v2. Remove whitespace addition to mmu_context_hash64.c
