x86: Deactivate kernel options with extra overhead 
Deactivate CONFIG_CONTEXT_TRACKING_USER_FORCE: Force user context
tracking: This is a testing feature which should not be activate in
production environments according to the Kconfig help. It adds an extra
overhead.

Deactivate CONFIG_RCU_NOCB_CPU_DEFAULT_ALL: Offload RCU callback
processing from all CPUs by default: This option should only be used in
aggressive HPC or real-time workloads which we do not have in OpenWrt.
For normal workloads it increases the number of context switches.

In the default Arch Linux kernel both options are not activated.
