[PATCH 2/4] time: add a notifier chain for when the system time is stepped
From: David Vrabel <david.vrabel@citrix.com>
The high resolution timer code gets notified of step changes to the
system time with clock_was_set() or clock_was_set_delayed() calls. If
other parts of the kernel require similar notification there is no
clear place to hook into.
Add a clock_was_set atomic notifier chain
(clock_was_set_notifier_list) and call this in place of
clock_was_set().

[RFC PATCH 00/35] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
