defconfig: rename kernel

cpufreq: interactive: prevents the frequency to directly raise above the
hispeed_freq from a lower frequency.

When the load was below go_hispeed_load, there is a possibility that
choose_freq() would return a frequency which would be higher than the
hispeed_freq. According to the policy we should first jump to the
hispeed_freq, stay there for above_hispeed_delay and then be allowed to
raise higher than that.

Added a check to prevent the frequency to be directly raised to
something higher than the hispeed_freq.
