Subject: sched/rt, c6x: Use CONFIG_PREEMPTION
X-Git-Tag: v5.15~4233^2~122
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=51466979c754d11e1e8da0e46a66218ffc7226ee;p=platform%2Fkernel%2Flinux-starfive.git

sched/rt, c6x: Use CONFIG_PREEMPTION

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT.
Both PREEMPT and PREEMPT_RT require the same functionality which today
depends on CONFIG_PREEMPT.

Switch the entry code over to use CONFIG_PREEMPTION.
