Subject: [PATCH v3 0/2] Intel-IOMMU: source-id checking for interrupt remapping

Support source-id checking for interrupt remapping, and then
isolates interrupts for guests/VMs with assigned devices.

Eric raised pci rebalance issue with VT-d. Yes, it's an issue now.
Linux needs to handle pci rebalance changes to DRHD scopes. It's
tricky to support it. This patch just supports source-id for
interrupt remapping, won't touch that.

The patchset can be applied on linux-2.6-tip tree.

v2 -> v3 changelog:
	As Ingo suggested, restructured some code and fixed some code
style issues. 	

v1 -> v2 changelog:
        Access PCI directly (read_pci_config_byte) to parse IOAPIC,
instead of PCI related discovery, because PCI subsystem is not
initialized at that time.


Weidong Han (2):
  Intel-IOMMU, intr-remap: set the whole 128bits of irte when
    modify/free it
