We can deliver certain interrupts, notably MSIX, from atomic context. Here's an untested patch to do this (compiled only).
Changes from v2: Don't inject broadcast interrupts directly Changes from v1: Tried to address comments from v1, except unifying with kvm_set_irq: passing flags to it looks too ugly. Added a comment.
