a way to qualify wakeups during poll") added more aggressive shrinking of the polling interval if the wakeup did not match some criteria. This still allows to keep polling enabled if the polling time was smaller that the current max poll time (block_ns <= vcpu->halt_poll_ns). Performance measurement shows that even more aggressive shrinking (shrink polling on any invalid wakeup) reduces absolute and relative (to the workload) CPU usage even further.
