In kernel/acpi/realmode/Makefile use the 'always'
variable to say that wakeup.bin should always
be made.
In acpi/Makefile we then do not need to specify the
requested target and we avoid the message from make:
`arch/x86/kernel/acpi/realmode/wakeup.bin' is up to date.
Add wakeup.lds to list af targets to avoid rebuilding
wakeup.bin - from Roland McGrath.

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]

Unify arch/x86/kernel/acpi/sleep*.c
Pretty trivial unification; when two functions differed, it was
usually in error handling, and better of the two was picked up.
