This reverts commit ef1134dd.

Sometimes back commit cfb00a35 ("arm64: jump_label: Ensure patched
jump_labels are visible to all CPUs") got merged into all stable
branches wherever applicable with citing a bug in static key which
does not synchronizes among the cpus and adds IPI to all cores to
fix this.

Kfence is one of the user of static key and recently, it has been
observed that after above commit during toggling kfence_allocation_key
IPI is being sent to the core which are there low power mode which
has regressed power numbers and after disabling CONFIG_KFENCE_STATIC_KEYS
we see workload improved in the range of 1% - 10% resulting in 1% - 4%
power savings for few audio playback, video decode & display cases and
with no regression on benchmarks.
