Hi,

I got the following with current git:

WARNING: arch/x86/kernel/cpu/cpufreq/powernow-k8.o(.exit.text+0x1c): Section mismatch in reference from the function cleanup_module() to the variable .cpuinit.data:cpb_nb
The function __exit cleanup_module() references
a variable __cpuinitdata cpb_nb.
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __cpuinitdata annotation of
cpb_nb so it may be used outside an init section.

Looks like it was introduced by
"powernow-k8: Add core performance boost support".

Oh yeah, Peter pointed it out to me earlier, we have a fix already:
https://patchwork.kernel.org/patch/102225/

Thanks.
