Re: [PATCH 00/45] C++: Convert the kernel to C++

[H. Peter Anvin]

One thing I forgot to mention that would be quite useful is careful use 
of namespaces. For example, putting init functions in their own 
namespace would have not only make it a lot harder to call init 
functions from non-init functions by mistake (calling init::func() 
explicitly is a highly visible "I really do mean to do this."

However, it also let us do separate init versions of functions like 
cpu_feature_enable() that contain optimizations that aren't actually 
usable at init time (alternatives have not been applied.) The idea is 
*not* to change the code, but rather the compiler will simply prefer 
init:: functions from inside other init:: functions (a direct 
consequence of how namespaces work.)
