Message:

Switch the amd64 kernel (back) from 'large' to 'kernel' memory model.

• This makes the amd64 kernel 6% smaller and more comfortable to debug.
• Unlike in the original 'kernel' memory model implementation, KA2PA(PA2KA(x)) == x; for x from kernel identity.
• Memory outside of the kernel identity region continues to be available by the standard means.
