Rusty, here is just patch 1 (using bool as return value in notify API). Thanks.

Hi, this patch-set solves a hang situation when a vlan network device is hot-unplugged from a KVM guest. On System z there exists no handshake mechanism between host and guest when a device is hot-unplugged. The device is removed and no further I/O is possible. The guest is notified about the hard removal with a CRW machine check. As per architecture, the host must repond to any I/O operation

Aiming these for coming merge window. Nothing should change, but get ready for a non-guest-endian config transports, and > 32 features bits. Final one is just an overdue consolidation. Cheers, Rusty. Rusty Russell (7): virtio_config: introduce size-based accessors. virtio: use size-based config accessors. virtio_config: helpers for non-converting accessors. virtio_config: make

I've renewed this again, with some comments from HPA. I've tried to keep the new patches separate, so you can see the changes since we last discussed this (and so it's easy to back it out if we decide it's insane). I haven't even looked at the QEMU side so this is completely untested. Comments gratefully received! Rusty. Michael S Tsirkin (1): pci: add pci_iomap_range
