They must be zero'd out when the CPU is offline.
Patch 1/3 simply combines topology.c and cpu.c and introduces no new
functionality. It is a staging patch for 2/3. Patch 3/3 is a simple cleanup.
Prarit Bhargava (3):
drivers/base, Combine topology.c and cpu.
The information in /sys/devices/system/cpu/cpuX/topology
directory is useful for userspace monitoring applications and in-tree
utilities like cpupower & turbostat.
When down'ing a CPU the /sys/devices/system/cpu/cpuX/topology directory is
removed during the CPU_DEAD hotplug callback in the kernel.

The MSR exposure seems to be okay with the following statements:
- complete read of /dev/cpu/X/msr is bad, whitelist instead
- needs to be dependent on either CPU version or reading MSRs for support.
IIRC the Intel documentaton on the MSRs indicated that there are ways to

Thomas, any comment?
Looks good to me. The description could be cleaned up a bit but I'll let the

erruptible() puts each thread
