| |
The XEN config option enables the Xen paravirt_ops interface, which is installed when the kernel finds itself running under Xen.
Xen is no longer a sub-architecture, so the X86_XEN subarch config option has gone.
Xen is currently incompatible with PREEMPT, but this is fixed up later in the series.
