Keir,
 
I found there are two sysctls with conflicting same sysctl
no in the code. This looks like a issue caused by merging code from different
developers, and need fixing. 
 
xen/include/public/sysctl.h
 
#define
XEN_SYSCTL_cpu_hotplug       11
…
#define
XEN_SYSCTL_lockprof_op       11
 
 
Looks like this has come from changeset 20312:
 
Spinlock profiling (enable in build with
lock_profile=y)
 
Adds new tool xenlockprof to run from
dom0.
