So I'm referring to the 'This is required' wording here:

| Subject: [PATCH 14/41] x86: Rename __this_cpu_xxx_# operations to raw_cpu_xxx_#
|
| This is required now since the core portion expects a different 
| naming.
|
| Change the names from __this_cpu_xxxx_# to raw_cpu_xxxx_#.
|
| Also changes the uses of the x86 percpu primitives in preempt.h.
|
| This is required now since the core portion expects a different naming.

By what is this required - by the previous patch #13?

Also, the changelog indicates it's two changes - please split the 
patch in two if so.

(Tejun, please wait for this review to be complete before committing 
anything.)

Thanks,

	Ingo
