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 --- Reading git-diff-tree failed
