[PATCH] x86_64: Allow compilation on a 32bit biarch toolchain

This might help on distributions that use a 32bit biarch compiler.

First pass -m64 by default.

Secondly add some more .code32s because at least the Ubuntu biarch
32bit as called by gcc doesn't seem to handle -m64 -m32 as generated

And finally make sure the linker script can be preprocessed
with a 32bit cpp.

[PATCH] i386/x86-64: Don't IPI to offline cpus on shutdown

So why are we calling smp_send_stop from machine_halt?

We don't.

Looking more closely at the bug report the problem here
is that halt -p is called which triggers not a halt but
an attempt to power off.

machine_power_off calls machine_shutdown which calls smp_send_stop.

If pm_power_off is set we should never make it out machine_power_off
to the call of do_exit.  So pm_power_off must not be set in this case.
When pm_power_off is not set we expect machine_power_off to devolve
into machine_halt.

So how do we fix this?

Playing too much with smp_send_stop is dangerous because it
must also be safe to be called from panic.

It looks like the obviously correct fix is to only call
machine_shutdown when pm_power_off is defined.  Doing
that will make Andi's assumption about not scheduling
true and generally simplify what must be supported.

This turns machine_power_off into a noop like machine_halt
when pm_power_off is not defined.

If the expected behavior is that sys_reboot(LINUX_REBOOT_CMD_POWER_OFF)
becomes sys_reboot(LINUX_REBOOT_CMD_HALT) if pm_power_off is NULL
this is not quite a comprehensive fix as we pass a different parameter
to the reboot notifier and we set system_state to a different value
before calling device_shutdown().

Unfortunately any fix more comprehensive I can think of is not
obviously correct.  The core problem is that there is no architecture
independent way to detect if machine_power will become a noop, without
calling it.

KBUILD_BASENAME token.  With -mm1, the expansion is now a quote-delimited
string, so there needs to be a definition of it.

Since kernel-offsets.c is basically the same as other arches' asm-offsets.c,
and those seem to build OK, this patch turns kernel-offsets.c into
asm-offsets.c.  kernel-offsets.c is in arch/um/sys-$(SUBARCH), i.e.  sys-i386
and sys-x86_64, while kbuild expects it to be in arch/um/kernel.
kernel-offsets.c is moved to
arch/um/include/sysdep-$(SUBARCH)/kernel-offsets.h, which is included by
arch/um/kernel/asm-offsets.c.  With that, include/asm-um/asm-offsets.h is
generated automatically.  kernel-offsets.h continues to exist because it needs
to be accessible to userspace UML code, and include/asm-um isn't.  So, a
symlink is made from arch/um/include/kernel-offsets.h to
include/asm-um/asm-offsets.h.
