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

[Alexander Gordeev]

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
