Subject: x86_64 add missing enter_idle() calls
From: Stephane Eranian <eranian@xxxxxxxxxx>
Unless I am mistaken, I think we are missing some calls to enter_idle() in the
x86_64 tree. The following patch adds a bunch of missing enter_idle()
callbacks for some of the "direct" interrupt handlers.
Add missing enter_idle() calls to most of the "direct" interrupt handlers.
