The patch titled
cpuidle: make cpuidle sysfs driver/governor switch off by default
has been removed from the -mm tree. Its filename was
cpuidle-make-cpuidle-sysfs-driver-governor-switch-off-by-default.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: cpuidle: make cpuidle sysfs driver/governor switch off by default
From: Venki Pallipadi <[EMAIL PROTECTED]>
Make default cpuidle sysfs to show current_governor and current_driver in
read-only mode. More elaborate available_governors and available_drivers with
writeable current_governor and current_driver interface only appear with
"cpuidle_sysfs_switch" boot parameter.
