Subject[PATCH 21/85] ACPICA: x2APIC support: changes for MADT and SRAT ACPI tables
From: Bob Moore <robert.moore@intel.com>

Support for the x2APIC. There are 2 new subtables for the MADT and
one new subtable for the SRAT. Includes disassembler and acpisrc
support. Data from the Intel 64 Architecture x2APIC Specification,
June 2008.
