Subject: fix a shutdown regression in intel_idle
From: Shaohua Li <[email protected]>
commit ec30f343d61391ab23705e50a525da1d55395780 upstream.
Fix a shutdown regression caused by 2a2d31c8dc6f ("intel_idle: open
broadcast clock event"). The clockevent framework can automatically
shutdown broadcast timers for hotremove CPUs. And we get a shutdown
regression when we shutdown broadcast timer for hot remove CPU, so just
delete some code.
Also fix some section mismatch.
