[PATCH/RFC] replace get_scheduled_cycles with sched_clock paravirt_op
Subject: Add a sched_clock paravirt_op
The tsc-based get_scheduled_cycles interface is not a good match for
Xen's runstate accounting, which reports everything in nanoseconds.
This patch replaces this interface with a sched_clock interface, which
matches both Xen and VMI's requirements.
In order to do this, we:

Here's a repost of the paravirt_ops update series I posted the other day.
Since then, I found a few potential bugs with patching clobbering,
cleaned up and documented paravirt.h and the patching machinery.

necessary for Xen.
The brief overview:
add-MAINTAINERS.patch - obvious
remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed
paravirt-nop.patch - mark nop operations consistently
paravirt-pte-accessors.patch - operations to pack/unpack

[patch 00/34] Xen-pv_ops: Xen guest implementation for paravirt_ops interface
Hi Andi,
This patch series implements the Linux Xen guest as a paravirt_ops
backend. The features in implemented this patch series are:
* domU only
* UP and SMP guest support (NEW!)
* dynamic ticks (NEW!)
* writable pagetables, with late pinning/early unpinning
(no shadow pagetable support)
* supports both PAE and non-PAE modes
(non-PAE may be broken at the moment)
* xen hvc console
