Subject: [PATCH v4 0/2] Forcibly enable some MISC_ENABLE features on Intel

Intel allows BIOS or the OS to enable or disable some CPU fueatures via
IA32_MISC_ENABLE.  I have machines that don't enable fast strings or
monitor/mwait in BIOS, so do it on bootup instead.

Changes from v3:
 - Don't display CPU index (and therefore don't break !SMP build)
 - Don't display "Failed to enable..." when kmemcheck is on

Changes from v2:
 - Don't linebreak printk messages (for ease of grepping)
 - Use printk_once
 - Update the "Disabled fast string operations" message

Changes from v1:
 - Display FW_WARN messages.
 - Don't change the kmemcheck message.
 - Improve the fast string comment.
 - Improve the changelogs.

Andy Lutomirski (2):
  x86: Enable fast strings on Intel if BIOS hasn't already
  x86: Enable monitor/mwait on Intel if BIOS hasn't already
