I have tested on multiple Intel platforms. I didn't see this issue. I don't have an AMD.

Jeremy, I am away this week. I will give you access to my git repo by mid next week.

I have ported xenoprof to linux-pvops.

- All the changes/clean-ups are limited to linux modules
(except a xen
interface for kernel space mappings).
- Calls are switched to xen by checking for xen_initial_domain. Is
there a better way of handling such modules with pvops ?

On my AMD system, I'm seeing warning from xen_apic_write
coming from perf_counters_lapic_init().  Do your patches
resolve the issue?
