Good to know! So I worry too much here.
But still, given hrtimer interrupt is called with IRQ disabled, getting stuck in a hrtimer callback could also block IPI handler, therefore causing soft lockups.
Let me know if you want me to adjust the changelog for this.
yep, it's confusing, I think it should be removed from changelog
