    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."
