In switch_mmu_context() if we call steal_context_smp() to get a context to use we shouldn't fall through and than call steal_context_up(). Doing so can be problematic in that the 'mm' that steal_context_up() ends up using will not get marked dirty in the stale_map[] for other CPUs that might have used that mm. Thus we could end up with stale TLB entries in the other CPUs that can cause all kinda of havoc. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
