the cpu count is changed accordingly: now, what matters is
online cpus.
Also, we add those functions for x86_64

Impressing friends is a very important thing.
Do it in a separate function to make it even more
explicit, and ease integration.

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.

smpboot_{32,64}.c to smpboot.c
cpu_callin_map is put temporarily in smp_64.h (already
exists in smp_32.h), and will soon be merged.

this patches moves prefill_possible_map() to smpboot.c
Right now it is x86_64-specific, but nothing intrinsically
prevents it to be used by i386
