Wondering why the main kernel has been reconfigured from
CONFIG_NO_HZ_IDLE to CONFIG_NO_HZ_FULL?
The config help has this to say regarding CONFIG_NO_HZ_FULL: "This is
implemented at the expense of some overhead in user <-> kernel transitions: syscalls, exceptions and interrupts. Even when it's dynamically off."
