22: * Clean up linux emulation code to make it architecture-independent
23: * as much as possible.
24: *
25: * * linux: Renamed from linuxdev.
26: * * Makefile.in (objfiles): Add linux.o instead of linuxdev.o.
27: * (MAKE): New variable. Used for the linux.o target.
28: * * configure.in: Add AC_CHECK_TOOL(MAKE, make).
29: * * i386/i386/spl.h: Include <i386/ipl.h>, for compatibility with
30: * OSF Mach 3.0. Suggested by Elgin Lee <[email protected]>.
31: * * linux/src: Renamed from linux/linux.
32: * * linux/dev: Renamed from linux/mach.
33: * * linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h,
34: * instead of mach/include/linux/autoconf.h.
35: * * Makefile.in (all): Target ../linux.o instead of ../linuxdev.o.
36: * * linux/dev/drivers/block/genhd.c: Include <machine/spl.h> instead
37: * of <i386/ipl.h>.
38: * * linux/dev/drivers/net/auto_irq.c: Remove unneeded header files,
39: * <i386/ipl.h> and <i386/pic.h>.
40: * * linux/dev/init/main.c: Many i386-dependent codes moved to ...
41: * * linux/dev/arch/i386/irq.c: ... here.
42: * * linux/dev/arch/i386/setup.c: New file.
43: * * linux/dev/arch/i386/linux_emul.h: Likewise.
44: * * linux/dev/arch/i386/glue/timer.c: Merged into sched.c.
45: * * linux/dev/arch/i386/glue/sched.c: Include <machine/spl.h> instead
46: * of <i386/ipl.h>, and moved to ...
47: * * linux/dev/kernel/sched.c: ... here.
48: * * linux/dev/arch/i386/glue/block.c: Include <machine/spl.h> and
49: * <linux_emul.h>, instead of i386-dependent header files, and
50: * moved to ...
51: * * linux/dev/glue/blocl.c: ... here.
52: * * linux/dev/arch/i386/glue/net.c: Include <machine/spl.h> and
53: * <linux_emul.h>, instead of i386-dependent header files, and
54: * moved to ...
55: * * linux/dev/glue/net.c: ... here.
56: * * linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ...
57: * * linux/dev/glue/misc.c: ... here.
58: * * linux/dev/arch/i386/glue/kmem.c: Moved to ...
59: * * linux/dev/glue/kmem.c: ... here.
