Subject: [PATCH 4/9] powerpc: Add local_flush_tlb_mm() to SW loaded TLB implementations
Date: Mon, 08 Dec 2008 16:40:14 +1100 [thread overview]
Message-ID: <20081208054121.3EDD6DDE24@ozlabs.org> (raw)
In-Reply-To: <1228714789.103940.266501677728.qpush@grosgo>
This adds a local_flush_tlb_mm() call as a pre-requisite for some
SMP work for BookE processors
