Subject: [PATCH] MIPS: lantiq: register smp_ops on non-smp platforms
|
|
|
|
Lantiq uses a common kernel config for devices with 24Kc and 34Kc cores.
|
|
The changes made previously to add support for interrupts on all cores
|
|
work on 24Kc platforms with SMP disabled and 34Kc platforms with SMP
|
|
enabled. This patch fixes boot issues on Danube (single core 24Kc) with
|
|
SMP enabled.
|
|
|
|
Fixes: 730320fd770d ("MIPS: lantiq: enable all hardware interrupts on second VPE")
