powerpc: Add write barrier before enabling DTL flags Currently, we don't enforce any ordering for updates to the lppaca when enabling dtl logging, so we may end up enabling logging before the index fields have been established. This change adds a smp_wmb() before doing the actual enable. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
