FWIW, the next step (still not pushed there) is to move arch/um/sys-x86 to
arch/x86/um, with arch/um/os-Linux/sys-x86 becoming arch/x86/um/os-Linux,
Kconfig.x86 moving to arch/x86/um/Kconfig and Makefile-x86 - to
arch/x86/um/Makefile.defs.  Next after that - arch/powerpc/um (and yes,
it means resurrected uml/ppc port; for now - only ppc32, since I have no
ppc64 boxen to test on).
