[PATCH 0/3] iommu/amd: Enable x2APIC support

[Suravee Suthikulpanit]

This series enable x2APIC support for AMD platform by enabling
AMD IOMMU XT mode to allow interrupt remapping with 32-bit
destination APIC ID.

For full x2APIC support, the following patches are also required
(already available in v4.18-rc1)
  * 6c4f5abaf356 ("x86/CPU: Modify detect_extended_topology() to return result")
  * 3986a0a805e6 ("x86/CPU/AMD: Derive CPU topology from CPUID function 0xB when available")

Thanks,
Suravee
