Joerg Roedel 6b474b8224 iommu/amd: Add initialization routines for AMD interrupt remapping
Add the six routines required to setup interrupt remapping
with the AMD IOMMU. Also put it all together into the AMD
specific irq_remap_ops.

Joerg Roedel 05152a0494 iommu/amd: Add slab-cache for irq remapping tables
The irq remapping tables for the AMD IOMMU need to be
aligned on a 128 byte boundary. Create a seperate slab-cache
to guarantee this alignment.

Suresh Siddha 7eb9ae0799 irq/apic: Use config_enabled(CONFIG_SMP) checks to clean up irq_set_affinity() for UP
Move the ->irq_set_affinity() routines out of the #ifdef CONFIG_SMP
sections and use config_enabled(CONFIG_SMP) checks inside those
routines. Thus making those routines simple null stubs for
!CONFIG_SMP and retaining those routines with no additional
runtime overhead for CONFIG_SMP kernels.

Cleans up the ifdef CONFIG_SMP in and around routines related to
irq_set_affinity in io_apic and irq_remapping subsystems.
