Merge branch 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 platform changes from Ingo Molnar:
 "This tree mostly involves various APIC driver cleanups/robustization,
  and vSMP motivated platform callback improvements/cleanups"

Fix up trivial conflict due to printk cleanup right next to return value
change.

* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (29 commits)
  Revert "x86/early_printk: Replace obsolete simple_strtoul() usage with kstrtoint()"
  x86/apic/x2apic: Use multiple cluster members for the irq destination only with the explicit affinity
  x86/apic/x2apic: Limit the vector reservation to the user specified mask
  x86/apic: Optimize cpu traversal in __assign_irq_vector() using domain membership
  x86/vsmp: Fix vector_allocation_domain's return value
  irq/apic: Use config_enabled(CONFIG_SMP) checks to clean up irq_set_affinity() for UP
  x86/vsmp: Fix linker error when CONFIG_PROC_FS is not set
  x86/apic/es7000: Make apicid of a cluster (not CPU) from a cpumask
  x86/apic/es7000+summit: Always make valid apicid from a cpumask
  x86/apic/es7000+summit: Fix compile warning in cpu_mask_to_apicid()
  x86/apic: Fix ugly casting and branching in cpu_mask_to_apicid_and()
  x86/apic: Eliminate cpu_mask_to_apicid() operation
  x86/x2apic/cluster: Vector_allocation_domain() should return a value
  x86/apic/irq_remap: Silence a bogus pr_err()
  x86/vsmp: Ignore IOAPIC IRQ affinity if possible
  x86/apic: Make cpu_mask_to_apicid() operations check cpu_online_mask
  x86/apic: Make cpu_mask_to_apicid() operations return error code
  x86/apic: Avoid useless scanning thru a cpumask in assign_irq_vector()
  x86/apic: Try to spread IRQ vectors to different priority levels
  x86/apic: Factor out default vector_allocation_domain() operation
