x86, irq: Move irq_remapped out of x86 core code (2013-01-24 18:29:33 +0100)

Cleanup X86 IOAPIC code from interrupt remapping details

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.

The code was rebased to v3.8-rc4 and tested on systems with AMD-Vi and
Intel VT-d (both capable of interrupt remapping). The systems were
tested with IOMMU enabled and with IOMMU disabled. No issues were found.

Joerg Roedel (19):
x86, apic: Move irq_remapping_enabled checks into IRQ-remapping code
x86, apic: Mask IO-APIC and PIC unconditionally on LAPIC resume
x86, io_apic: Introduce x86_io_apic_ops.disable()
x86, io_apic: Introduce x86_io_apic_ops.print_entries for debugging
x86, hpet: Introduce x86_msi_ops.setup_hpet_msi
x86, msi: Use IRQ remapping specific setup_msi_irqs routine
x86, io_apic: Introduce set_affinity function pointer
x86, io_apic: Convert setup_ioapic_entry to function pointer
x86, io_apic: Move irq_remapping_enabled checks out of check_timer()
x86, io_apic: Remove irq_remapping_enabled check in setup_timer_IRQ0_pin
x86, irq: Move irq_remapping_enabled declaration to iommu code
x86, irq: Add data structure to keep AMD specific irq remapping information
x86, io-apic: Move CONFIG_IRQ_REMAP code out of x86 core
x86, io-apic: Remove !irq_remapped() check from __target_IO_APIC_irq()
x86, irq: Move irq_remapped() check into free_remapped_irq
x86, irq: Introduce setup_remapped_irq()
x86, msi: Introduce x86_msi.compose_msi_msg call-back
x86, io_apic: Introduce eoi_ioapic_pin call-back
x86, irq: Move irq_remapped out of x86 core code
