[PATCH] remove fixup_cpu_present_map()
Since the addition of boot_cpu_init(), fixup_cpu_present_map() has been a
no-op. That's because fixup_cpu_present_map() won't touch cpu_present_map if
it has any bits set, and boot_cpu_init() sets a bit.
So remove fixup_cpu_present_map().
A consequence of this (actually of the boot_cpu_init() change) is that the
architecture _must_ populate cpu_present_map itself (probably in
smp_prepare_cpus()). fixup_cpu_present_map() won't do it any more.
If the architecture doesn't do this, it'll only bring up a single CPU.
The other side effect (though less serious) is that smp_prepare_boot_cpu() no
longer needs to mark the boot cpu in the online and present maps -
boot_cpu_init() does that for everyone (to make early printks work).
