This is a combo of Hou's series to clean up the "IRQs disabled" mess(es), and
my one-off patch to drop "cache" from a few names that escalated.  I tagged it
v4 since Hou's last posting was v3, and this is much closer to Hou's series
than anything else.

v4:
 - Tweak changelog regarding the "cache" rename to try and better capture
   the details of how .curr is used. [Yan]
 - Synchronize the cache immediately after TD-Exit to minimize the window
   where the cache is stale (even with the reboot change, it's still nice to
   minimize the window). [Yan]
 - Leave the user-return notifier registered on reboot/shutdown so that the
   common code doesn't have to be paranoid about being interrupted.
