362 Support the ACPI PM timer for time keeping. This is slow,
363 but is useful on some chipsets without HPET on systems with more
364 than one CPU. On a single processor or single socket multi core
365 system it is normally not required.
366 When the PM timer is active 64bit vsyscalls are disabled
367 and should not be enabled (/proc/sys/kernel/vsyscall64 should
368 not be changed).
369 The kernel selects the PM timer only as a last resort, so it is
