asm-generic: add generic versions of common headers
These are all kernel internal interfaces that get copied
around a lot. In most cases, architectures can provide
their own optimized versions, but these generic versions
can work as well.
I have tried to use the most common contents of each
header to allow existing architectures to migrate easily.
Thanks to Remis for suggesting a number of cleanups.
