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

Pull x86/apic changes from Ingo Molnar:
 "Main changes:

   - Multiple MSI support added to the APIC, PCI and AHCI code - acked
     by all relevant maintainers, by Alexander Gordeev.

     The advantage is that multiple AHCI ports can have multiple MSI
     irqs assigned, and can thus spread to multiple CPUs.

     [ Drivers can make use of this new facility via the
       pci_enable_msi_block_auto() method ]

   - x86 IOAPIC code from interrupt remapping cleanups from Joerg
     Roedel:

     These patches move all interrupt remapping specific checks out of
     the x86 core code and replaces the respective call-sites with
     function pointers.  As a result the interrupt remapping code is
     better abstraced from x86 core interrupt handling code.

   - Various smaller improvements, fixes and cleanups."
