commit f0bb2d50dfcc519f06f901aac88502be6ff1df2c upstream. The latest gcc-7.0.1 snapshot reports a new warning: virtio/virtio_balloon.c: In function 'update_balloon_stats': virtio/virtio_balloon.c:258:26: error: 'events[2]' is used uninitialized in this function [-Werror=uninitialized] virtio/virtio_balloon.c:260:26: error: 'events[3]' is used uninitialized in this

These changes were as in linux-next as e1c287efcd4cf688564ed1112d032b5dac29b159 - I tweaked the commit log slightly. Too many people were complaining of warnings and errors in virtio so I decided revert is the safest path forward right now.

This series fixes issues with variable initialization in the virtio balloon driver which manifest as the driver sending invalid memory stats to the host. v1->v2: * Call update_balloon_stats instead of filling the buffer with invalid tags. * Add BUG_ON to update_balloon_stats to formalize the invariant that all slots in the buffer must be initialized. v2->v3: * Remove BUG_ON and

This lets IRQ layer handle dispatching IRQs to separate handlers for the case where we don't have per-VQ MSI-X vectors, and allows us to greatly simplify the code based on the assumption that we always have interrupt vector 0 (legacy INTx or config interrupt for MSI-X) available, and any other interrupt is request/freed throught the VQ, even if the actual interrupt line might be shared in some
