Fix this by reintroducing asm/smp.h include in apic.c - later on
I will fix this by removing non-smp data from smp.h

Also fix the __inquire_remote_apic() prototype/inline.

Ingo noticed that using signed arithmetic seems to confuse the gcc
inliner, and make it potentially decide that it's all too complicated.

(Yeah, yeah, it's a constant. It's always positive. Still..)

Impact: cleanup, solve 80 columns wrap problems

It would be cleaner to rename all the mpc->mpc_X fields to
mpc->X - that alone would give 4 characters per usage site.
(we already know that it's an 'mpc' entity -
no need to duplicate that in the field too)

Impact: use new cpumask API to reduce memory and stack usage

Allocate the following local cpumasks based on the number of cpus that
are present.  References will use new cpumask API.  (Currently only
modified for x86_64, x86_32 continues to use the *_map variants.)

    cpu_callin_mask
    cpu_callout_mask
    cpu_initialized_mask
    cpu_sibling_setup_mask

Provide the following accessor functions:

    struct cpumask *cpu_sibling_mask(int cpu)
    struct cpumask *cpu_core_mask(int cpu)

Other changes are when setting or clearing the cpu online, possible
or present maps, use the accessor functions.

Impact: Reduce future system panics due to cpumask operations using NR_CPUS

Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are
allocated based on nr_cpu_ids, these extra bits will not be defined.

Also some other minor updates:

   * change in to use cpu accessor function set_cpu_present() instead of
     directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c]

   * use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c]

   * optimize some cpu_mask_to_apicid_and functions.
