We use the same routing as x86_64, moved now to setup.c.
Just with a few ifdefs inside.
Note that this routing uses prefill_possible_map().
It has the very nice side effect of allowing hotplugging of
cpus that are marked as present but disabled by acpi bios.

as x86_64

Do tests before do_boot_cpu in native_cpu_up for i386.
Tests are a little bit broader than originally, and are the
same as x86_64. Test for smp_callin is not applicable right now
and is deferred.

This patch does not change the behaviour of x86_64, since APIC_INTEGRATED
is always defined as (1). But the code now matches exactly i386 version
(well, this part of the code, at least)

This is done so we call setup_secondary_clock() in the same place x86_64
does. A separate patch for this is appearantly not needed. But clock
initialization is such a delicate thing, that it's safer to do this way

This patch replaces apic_read() for apic_read_around()
and apic_write for apic_write_around() in smpboot_64.c
We do it to have a common usage between x86_64 and i386.
In the former, it will always simply expand to apic_write
