| |
Function smp_send_reschedule is standard kernel ABI, which is defined header file include/linux/smp.h, however on LoongArch it is defined as inline function, so that kernel module can not use this function.
Now define smp_send_reschedule as general function, and add EXPORT_SYMBOL_GPL on this function, so that kernel modules can use it.
