This patch lets interrupt handler functions have their natural type (ie. exactly match the data pointer type); for transition it allows the old irq_handler_t type as well. To do this it uses a gcc extension, cast-to-union, which allows a type to be cast to any type within the union. When used in a wrapper macro, it's a simple way of allowing one of several types. (Some drivers now need to

Rusty, here is just patch 1 (using bool as return value in notify API). Thanks. Heinz Graalfs (9): virtio_ring: change host notification API virtio_ring: let virtqueue_{kick()/notify()} return a bool virtio_net: verify if virtqueue_kick() succeeded virtio_test: verify if virtqueue_kick() succeeded virtio_ring: add new function virtqueue_is_broken() virtio_blk: verify if queue is

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

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
