From d99c4022f60a9aa3a8dc6b7d71f3d0998c696912 Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Sat, 10 Sep 2005 19:44:56 +0200 Subject: [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.
