[PATCH] uml: inline mk_pte and various friends
Turns out that, for UML, a *lot* of VM-related trivial functions are not inlined but rather normal functions. In other sections of UML code, this is justified by having files which interact with the host and cannot therefore include kernel headers, but in this case there's no such justification. I've had to turn many of them to macros because of missing declarations. While doing this, I've decided to reuse some already existing macros.
