Mark the function local_allocate_threshold_blocks() with __cpuinit,
in order to remove the following section mismatch messages:

WARNING: arch/x86/kernel/cpu/mcheck/built-in.o(.text+0x1363): Section mismatch in reference from the function local_allocate_threshold_blocks() to the function .cpuinit.text:allocate_threshold_blocks()
The function local_allocate_threshold_blocks() references
the function __cpuinit allocate_threshold_blocks().
This is often because local_allocate_threshold_blocks lacks a __cpuinit
annotation or the annotation of allocate_threshold_blocks is wrong.

Impact: Reduce memory usage, use new API.

This is part of an effort to reduce structure sizes for machines
configured with large NR_CPUS.  cpumask_t gets replaced by
cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or
struct cpumask * (large NR_CPUS).

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.
