a8db8453ff x86: merge smp_prepare_boot_cpu
it is practically the same between arches now, so it is
moved to smpboot.c. Minor differences (gdt initialization)
live inside an ifdef

cb3c8b9003 x86: integrate do_boot_cpu
This is a very large patch, because it depends on a lot
of auxiliary static functions. But they all have been modified
to the point that they're sufficiently close now. So they're just
merged in smpboot.c

7cc3959ecd x86: move {un}map_cpu_to_logical_apicid to smpboot.c
Move map_cpu_to_logical_apicid() and unmap_cpu_to_logical_apicid()
to smpboot.c. They take together all the bunch of static functions
they rely upon

f6bc402909 x86: include mach_apic.h in smpboot_64.c and smpboot.c
After the inclusion, a lot of files needs fixing for conflicts,
some of them in the headers themselves, to accomodate for both
i386 and x86_64 versions.

[ mingo@elte.hu: build fix ]

f68e00a32b x86: move impress_friends and smp_check to cpus_done
the cpu count is changed accordingly: now, what matters is
online cpus.
Also, we add those functions for x86_64

904541e2f7 x86: allow user to impress friends.
Impressing friends is a very important thing.
Do it in a separate function to make it even more
explicit, and ease integration.

91718e8d13 x86: unify setup_trampoline
setup_trampoline() looks very similar between architectures, and this
patch unifies them. The i386 version allocates bootmem memory, while
the x86_64 version uses a fixed address.

In this patch, we initialize the global trampoline_base to the x86_64 version,
and i386 allocation can later override it.
