Your comment that the assignment is redundant is correct, but I am afraid that this fix is also wrong. In particular, it would not cause exit_lmode and enter_rmode to be called. You are not describing which call to kvm_mmu_reset_context was messed up, so I'm not sure how your patch is fixing things. Paolo
