openrisc: fix initial preempt state for secondary cpu tasks (b441aab7) · Commits · 戴 / test

During SMP testing we were getting the below warning after booting the secondary cpu: [ 0.060000] BUG: scheduling while atomic: swapper/1/0/0x00000000 This change follows similar patterns from other architectures to start the schduler with preempt disabled. Signed-off-by:
