Jung-uk Kim e374a321fe Add a tunable "debug.hwpstate_verify" to check P-state after changing it and
turn it off by default.  It is very inefficient to verify current P-state of
each core, especially for CPUs with many cores.  When multiple commands are
requested to the same power domain before completion of pending transitions,
the last command is executed according to the manual.  Because requests are
serialized by the caller, all cores will receive the same command for each
call.  Do not call sched_bind() and sched_unbind().  It is redundant because
the caller does it anyway.
