It is the cost of 'make LOCALVERSION=x' vs. 'make LOCALVERSION=y'.

Too many drivers will be recompiled for no good reason as of today.
I claim no consumer below drivers/ and sound/ has a valid usecase for version.h.
But, someone else has to take the energy and argue them out of the tree.

With the proposed change every consumer of asm-generic/mshyperv.h will be dirty,
see 'touch include/asm-generic/mshyperv.h' for the impact. Therefore I think
only the two existing c files should include this header, in case the provided
information has a true value for the consumer.
