    Move wakeup code to .c, so that video mode setting code can be shared
    between boot and wakeup. Remove nasty assembly code in 64-bit case by
    re-using trampoline code. Stack setup was fixed to clear high 16bits
    of %esp, maybe that fixes some machines.
    
    .c code sharing and morse code was done H. Peter Anvin, Sam Ravnborg
    reviewed kbuild related stuff, and it seems okay to him. Rafael did
    some cleanups.
    
    [rjw:
    * Made the patch stop breaking compilation on x86-32
    * Added arch/x86/kernel/acpi/sleep.h
    * Got rid of compiler warnings in arch/x86/kernel/acpi/sleep.c
    * Fixed 32-bit compilation on x86-64 systems
    * Added include/asm-x86/trampoline.h and fixed the non-SMP
      compilation on 64-bit x86
    * Removed arch/x86/kernel/acpi/sleep_32.c which was not used
    * Fixed some breakage caused by the integration of smpboot.c done
      under us in the meantime]
