Introducing this Kbuild file allow us to:
make arch/x86/
And thus building all the core part of x86.

Impact: cleanup
Instead of using CLEAN_FILES in arch/x86/Makefile, add generated files
to targets in arch/x86/boot/Makefile, so they will get naturally
cleaned up by "make clean".

Impact: cleanup
Remove targets that were used for zImage only, and Makefile
infrastructure that was there to support the zImage/bzImage split.

Impact: no default -fno-stack-protector if stackp is enabled, cleanup
Stackprotector make rules had the following problems.
* cc support test and warning are scattered across makefile and
kernel/panic.c.
* -fno-stack-protector was always added regardless of configuration.
Update such that cc support test and warning are contained in makefile
and -fno-stack-protector is added iff stackp is turned off. While at
it, prepare for 32bit support.

Remove the 32-bit subarchitecture support code.
All subarchitectures but Voyager have been converted. Voyager will be
done later or will be removed.
Signed-off-by: Ingo Molnar <mingo@elte.hu>
Remove remaining bits of the subarchitecture code. Now that all the
special platforms are runtime probed and runtime handled, we can remove
these facilities.

this is the big move: flip over VISWS to generic arch support.
From this commit on CONFIG_X86_VISWS is just another (default-disabled)
option that turns on certain quirks - no other complications.

... so it could fall back to normal numa and we'd reduce the impact of the
NUMAQ subarch.
NUMAQ depends on GENERICARCH
also decouple genericarch numa from acpi.
also make it fall back to bigsmp if apicid > 8.

If the user selects the stack-protector config option, but does not have
a gcc that has the right bits enabled (for example because it isn't build
with a glibc that supports TLS, as is common for cross-compilers, but also
because it may be too old), then the runtime test fails right now.
This patch adds a warning message for this scenario. This warning accomplishes
two goals
1) the user is informed that the security option he selective isn't available
2) the user is suggested to turn of the CONFIG option that won't work for him,
and would make the runtime test fail anyway.

this patch allows x86_64 to use subarch mach_ headers
in practice, since x86_64 does not have any subarch, it
will use mach_default. But it will allow for substantially
less code duplication

Copy x86_64 and add a head32.c so we can start moving early
architecture initialization out of assembly.

I suggest to make the vdso_install step independent as
in following patch.
This solves the issue at ahnd and still gives us the posibility
to install the files should they be needed.

This paves the way for multiple architecture support. Note that while
ioapic.c could potentially be shared with ia64, it is also moved.
