This patch is preparation for replacing most ".data.cacheline_aligned"
in the kernel with macros, so that the section name can later be
changed without having to touch a lot of the kernel.

The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections.  This requires renaming all magic sections with names
of the form ".data.foo".
