From da998a2aecd3f15eca5385e1122610890039c4df Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 5 May 2005 16:15:27 -0700 Subject: [PATCH] [PATCH] uml: cross-build support : mk_task and mk_constants helpers in arch/um/util (mk_task and mk_constants) converted. That's it - none of the helpers depends on build and target being the same architecture anymore.
