...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 u...

...virtio_pci driver, but instead of building on top of emulated PCI this driver is making use of the platform bus together with driver specific callbacks. The virtio platform driver can be seen as a reusable implementation of the lguest virtio driver - in fact, most code is just taken directly from lguest_device.c and reworked to fit the platform device driver abstraction. The first patch breaks out code that can be shared between lguest and the virtio platform driver. This code has been used to implement a mailbox interface between the two processor cores included in the sh7372 SoC. The sh7372 contains o...
