Yes:-P

As mentioned in the commit description, the content of the header is 
only used by code in arch/arm/mach-tegra/. By moving the header file out 
of a directory that's part of the include path, we ensure that code 
(such as drivers and core code) can't access the header without 
explicitly doing something unusual, which should ring alarm bells. This 
will help avoid future additions of code that touches Tegra internals 
rather than accessing functionality through standard/generic (or even 
custom but explicitly "exported") APIs.
