Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
* 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86: Skip cpus with apic-ids >= 255 in !x2apic_mode x86, x2apic: Allow "nox2apic" to disable x2apic mode setup by BIOS x86, x2apic: Fallback to xapic when BIOS doesn't setup interrupt-remapping x86, acpi: Skip acpi x2apic entries if the x2apic feature is not present x86, apic: Add probe() for apic_flat x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86' x86: Convert per-cpu counter icr_read_retry_count into a member of irq_stat x86: Add per-cpu stat counter for APIC ICR read tries pci, x86/io-apic: Allow PCI_IOAPIC to be user configurable on x86 x86: Fix the !CONFIG_NUMA build of the new CPU ID fixup code support x86: Add NumaChip support x86: Add x86_init platform override to fix up NUMA core numbering x86: Make flat_init_apic_ldr() available
