Subject: [PATCH v8 0/2] x86/devicetree: Enable multiprocessing

Current x86 implementation of Device Tree does not support multiprocessing,
and the bindings documentation describes the "reg" property of "cpu" nodes
as "CPU number" instead of hardware-assigned local APIC ID.

v8:
 * Fixed build error with CONFIG_X86_LOCAL_APIC=n reported by kbuild.

v7:
 * Change log update.

v6:
 * Calling of_property_read_u32() to get Local APIC ID from "reg".

 * DT documentation changes: corrected CPU node example and changed
   the "reg" property description.

v5:
 * Using the "reg" property to specify Local APIC ID.

Ivan Gorinov (2):
  of: Documentation: Specify local APIC ID in "reg"
  x86/devicetree: Use CPU description from Device Tree
