1. add register_softirq to register a softirq handler 2. rename exec_softirq to do_softirq; raise_softirq to fire_softirq. 3. in do_softirq call registered softirq handler not call the device softirq handle function directly 4. enable irq after vm exit and disable irq after the first call do_softirq before vm enter. 5. call do_softirq again when irq disabled to handle the risk unhandled softirq. 6. rename SOFTIRQ_DEV_ASSIGN to SOFTIRQ_PTDEV 7. remove SOFTIRQ_ATOMIC Signed-off-by: Li, Fei1 <fei1.li@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
