URL: https://svnweb.freebsd.org/changeset/base/276987

Log:
  MFC r265329:
  Disable ACPI and P4TCC throttling by default, following discussion on
  freebsd-current. These CPU speed control techniques are usually unhelpful
  at best. For now, continue building the relevant code into GENERIC so that
  it can trivially be re-enabled at runtime if anyone wants it.
  
  Relnotes:	yes
