From 68ca406930d6380b3be7ada5f15fcf85bfcbd552 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Fri, 19 Feb 2010 00:09:22 -0500 Subject: ACPI: delete the "acpi=ht" boot option acpi=ht was important in 2003 -- before ACPI was universally deployed and enabled by default in the major Linux distributions. At that time, there were a fair number of people who or chose to, or needed to, run with acpi=off, yet also wanted access to Hyper-threading. Today we find that many invocations of "acpi=ht" are accidental, and thus is it possible that it is doing more harm than good. In 2.6.34, we warn on invocation of acpi=ht. In 2.6.35, we delete the boot option.
