Yeah, that's fine. The idea is that osdep.h is where we fix up this kind of odd system-header bug, and we do it for everywhere, because otherwise it's too easy to forget to put in the "make this work on the oddball platform" code where it's needed. If you add the patch to change physmem.c, please cc: the author of the commit that added it (commit cdfa56c551bb) -- it looks a bit complicated so it's possible it is intentional. -- PMM
