  x86/platform: Move APIC ID validity check into platform APIC code
  x86/olpc/xo15/sci: Enable lid close wakeup control
  x86/geode/net5501: Add platform driver for Soekris Engineering net5501
  x86/geode/alix2: Supplement driver to include GPIO button support
  x86/mid/powerbtn: Use MSIC read/write instead of ipc_scu
  x86/mid/thermal: Turn off thermistor
  x86/mid/thermal: Add msic_thermal alias
  x86/mid/thermal: Convert to use Intel MSIC API
  x86/mid/scu_ipc: Remove Moorestown support
  x86/mid: Kill off Moorestown
  x86/mrst: Add msic_thermal platform support
  x86/config: Select MSIC MFD driver on Intel Medfield platform
  x86/mid: Remove Intel Moorestown
  x86/mrst: Set ISA bus type for fake MP IRQs
  x86/ioapic: Use legacy_pic to set correct gsi-irq mapping

-	  Lincroft (CPU core, graphics, and memory controller) and Langwell IOH.
-	  Unlike standard x86 PCs, Moorestown does not have many legacy devices
