b0e239ffad x86: rename mpc_config_oemtable to mpc_oemtable
Impact: cleanup, solve 80 columns wrap problems

mpc_config_oemtable should be renamed to mpc_oemtable.

The reason: the 'c' in MPC already means 'config' -
no need to repeat that in the type name.

The reason: the 'c' in MPC already means 'config' -

2fdf66b491 cpumask: convert shared_cpu_map in acpi_processor* structs to cpumask_var_t
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).

(Changes to powernow-k* by <travis>.)

9628937d5b x86: cleanup some remaining usages of NR_CPUS where s/b nr_cpu_ids
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.
