There are potential issues with
1. The size of per cpu reservation on bootup and the new percpu code that
allows allocations for per cpu areas during bootup. Sometime I wonder if I
should just go back to static allocs for that.
2. The topology information provided by the machine for the cache setup.
3. My code of course.
Bootlog would be appreciated.
