-	  ACPI enumerates both logical (a.k.a. Hyper-Threaded -- HT)
-	  and physical processors.  It is designed to obsolete several older
-	  specifications, including the MultiProcessor Specification (MPS),
-	  which supported only physical processors.
-
-	  CONFIG_ACPI_HT_ONLY includes just the minimal ACPI boot-time code
-	  necessary to enumerate logical processors and enable HT.
-
-	  CONFIG_ACPI includes this, plus IO APIC enumeration,
-	  and the hooks to run the ACPI AML interpreter for run-time events.
-
-	  When CONFIG_ACPI is selected, the command-line option "acpi=ht"
-	  is available to run just the ACPI boot-time code -- just as if
-	  only CONFIG_ACPI_HT_ONLY were selected.
-
-	  Note that "acpi=off" can be used to disable all ACPI code in the kernel.
