Subject: [PATCH 0/8] x86: apic: Cleanup and improve four apic operations

This patchset is an attempt to make some implementations of four apic
operations bit more sane and readable. It was booted with these apic drivers:
flat/flat, flat/phys, bigsmp, x2apic/cluster.

- patches 2,3,4	get rid of duplicate implementation of apic operations
- patch 5	tunes the way vectors are assigned
- patch 6	makes minor improvement to the code
- patches 7,8	are a continuation of 18374d8 commit

Attached patches:
  1/8 x86: apic: Trivial whitespace fixes
  2/8 x86: apic: Factor out default target_cpus() operation
  3/8 x86: apic: Factor out default cpu_mask_to_apicid() operations
  4/8 x86: apic: Factor out default vector_allocation_domain() operations
  5/8 x86: apic: Try to spread IRQ vectors to different priority levels
  6/8 x86: apic: Avoid useless scanning thru a cpumask in
    assign_irq_vector()
  7/8 x86: apic: Make cpu_mask_to_apicid() operations return error code
  8/8 x86: apic: Make cpu_mask_to_apicid() operations check cpu_online_mask
