[v5][PATCH] KVM: PPC: Book3E HV: call RECONCILE_IRQ_STATE to sync the software state

We enter with interrupts disabled in hardware, but we need to call RECONCILE_IRQ_STATE anyway to ensure that the software state is kept in sync instead of calling hard_irq_disable() directly. Signed-off-by: Tiejun Chen tiejun.c...@windriver.com --- v5: Fix one typo in the comment. v4: Fix one
