[PATCH] x86/paravirt: Avoid setting IF flag, if not necessary
Setting the IF flag can cause an VM exit. So we should avoid touching
the IF flag until absolutely necessary. This patch change the way
the paravirt arch_local_irq_restore() works by checking the previous
flags value and call arch_local_irq_enable() only if the IF flag was
set previously.
On a 32 vCPUs KVM guest running the AIM7 five-sec workload,
the performance increased slightly from 302136.32
