xen: add the Xenbus sysfs and virtual device hotplug driver This communicates with the machine control software via a registry residing in a controlling virtual machine. This allows dynamic creation, destruction and modification of virtual device configurations (network devices, block devices and CPUS, to name some examples).

xen: add xenfs to allow usermode <-> Xen interaction The xenfs filesystem exports various interfaces to usermode. Initially this exports a file to allow usermode to interact with xenbus/xenstore. Traditionally this appeared in /proc/xen. Rather than extending procfs, this patch adds a backward-compat mountpoint on /proc/xen, and provides a xenfs filesystem which can be mounted there.

xen: make -fstack-protector work under Xen -fstack-protector uses a special per-cpu "stack canary" value. gcc generates special code in each function to test the canary to make sure that the function's stack hasn't been overrun. On x86-64, this is simply an offset of %gs, which is the usual per-cpu base segment register, so setting it up simply requires loading %gs's base as normal. On i386, the stack protector segment is %gs (rather than the usual kernel percpu %fs segment register). This requires setting up the full kernel GDT and then loading %gs accordingly. We also need to make sure %gs is initialized when bringing up secondary cpus too. To keep things consistent, we do the full GDT/segment register setup on both architectures. Because we need to avoid -fstack-protected code before setting up the GDT and because there's no way to disable it on a per-function basis, several files need to have stack-protector inhibited. [ Impact: allow Xen booting with stack-protector enabled ] Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

xen: import arch generic part of xencomm On xen/ia64 and xen/powerpc hypercall arguments are passed by pseudo physical address (guest physical address) so that it's necessary to convert from virtual address into pseudo physical address. The frame work is called xencomm. Import arch generic part of xencomm.

xen: add balloon driver The balloon driver allows memory to be dynamically added or removed from the domain, in order to allow host memory to be balanced between multiple domains. This patch introduces the Xen balloon driver, though it currently only allows a domain to be shrunk from its initial size (and re-grown back to that size). A later patch will add the ability to grow a domain beyond its initial size.

xen: add /dev/xen/evtchn driver This driver is used by application which wish to receive notifications from the hypervisor or other guests via Xen's event channel mechanism.
