My test scenario is (almost) always make ARCH=um SUBARCH=i386 and run it on a 64bit system (it happened that I ran such kernels on 32bit systems and I never found problems in this transition). I always take care to use skas0 for 64bit guests or, for 32bit ones noprocmm or skas0 (both work, 1st is faster) if the host is a 64bit SKAS-patched one. > (like IA32 emulation inside a UML). This one is not expected to work now - it's a TODO feature since long time, but you'll already know we have other things before it on the list.
