Subject: From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
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
- HZ: set to 100Hz for now, to cut down on VCPU context switch rate.
This will be adapted to use tickless later.
