Subject: [PATCH 1/2] device-odroid-hc2: disable big.LITTLE switcher by default
The linux-edge kernel enables the BL_SWITCHER kernel option, which enables
an in-kernel big.LITTLE switcher - with it enabled, only 4 cores are enabled
at a time, and the kernel switches between the big and little cores. However,
in a server workload, it's more likely that a user wants all 8 cores to work
simultaneously.
Disable the switcher by default by providing the no_bL_switcher cmdline option.
It can still be re-enabled by writing 1 to /sys/kernel/bL_switcher/active.
