...says there's no clflush, ie. pre Pentium 4). (Discovered while playing with CPUID). - Rename many internal shadow pagetable functions & vars for clarity. - Remove cr3 member from "struct lguest": easy to calculate when needed. - Add comment on lack of interface stability. - Move lguest_devices array declaration from lguest.h to lguest_bus.h (it's only useful for devices). - Use read_cr0() and write_cr0() rather than open-coding them. - Use KERN_INFO on printk() for lguest initialization - Remove unneeded __attribute_used__ in core.c - Print out message when failing to run lguest un...

virtio: Virtio platform driver [PATCH 01/02] virtio: Break out lguest virtio code to virtio_lguest.c [PATCH 02/02] virtio: Add virtio platform driver These patches add a virtio platform driver to the Linux kernel. This platform driver has the same role as the virtio_pci driver, but instead of building on top of emulated PCI this driver is making use of the platform bus together with driver

At this point, no transports set any of the high 32 feature bits. Since transports generally can't (yet) cope with such bits, add BUG_ON checks to make sure they are not set by mistake.
