 *
 * 	Clean up linux emulation code to make it architecture-independent
 * 	as much as possible.
 *
 * 	* linux: Renamed from linuxdev.
 * 	* Makefile.in (objfiles): Add linux.o instead of linuxdev.o.
 * 	(MAKE): New variable. Used for the linux.o target.
 * 	* configure.in: Add AC_CHECK_TOOL(MAKE, make).
 * 	* i386/i386/spl.h: Include <i386/ipl.h>, for compatibility with
 * 	OSF Mach 3.0. Suggested by Elgin Lee <[e-mail]>.
 * 	* linux/src: Renamed from linux/linux.
 * 	* linux/dev: Renamed from linux/mach.
 * 	* linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h,
 * 	instead of mach/include/linux/autoconf.h.
 * 	* Makefile.in (all): Target ../linux.o instead of ../linuxdev.o.
 * 	* linux/dev/drivers/block/genhd.c: Include <machine/spl.h> instead
 * 	of <i386/ipl.h>.
 * 	* linux/dev/drivers/net/auto_irq.c: Remove unneeded header files,
 * 	<i386/ipl.h> and <i386/pic.h>.
 * 	* linux/dev/init/main.c: Many i386-dependent codes moved to ...
 * 	* linux/dev/arch/i386/irq.c: ... here.
 * 	* linux/dev/arch/i386/setup.c: New file.
 * 	* linux/dev/arch/i386/linux_emul.h: Likewise.
 * 	* linux/dev/arch/i386/glue/timer.c: Merged into sched.c.
 * 	* linux/dev/arch/i386/glue/sched.c: Include <machine/spl.h> instead
 * 	of <i386/ipl.h>, and moved to ...
 * 	* linux/dev/kernel/sched.c: ... here.
 * 	* linux/dev/arch/i386/glue/block.c: Include <machine/spl.h> and
 * 	<linux_emul.h>, instead of i386-dependent header files, and
 * 	moved to ...
 * 	* linux/dev/glue/blocl.c: ... here.
 * 	* linux/dev/arch/i386/glue/net.c: Include <machine/spl.h> and
 * 	<linux_emul.h>, instead of i386-dependent header files, and
 * 	moved to ...
 * 	* linux/dev/glue/net.c: ... here.
 * 	* linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ...
 * 	* linux/dev/glue/misc.c: ... here.
 * 	* linux/dev/arch/i386/glue/kmem.c: Moved to ...
 * 	* linux/dev/glue/kmem.c: ... here.
