arch/riscv/kernel/smp.c: In function 'handle_IPI':
arch/riscv/kernel/smp.c:195:44: error: 'cpu' undeclared (first use in this function)

This is with v5.15.81-124-g9269e46bc838.
The backport of commit 9b932aadfc47d seems wrong. The original version introduces
the cpu variable in handle_IPI(). The backport doesn't, and removes old_regs
instead.
Backport:
void handle_IPI(struct pt_regs *regs)
{
- struct pt_regs *old_regs = set_irq_regs(regs);
unsigned long *pending_ipis = &ipi_data[smp_processor_id()].bits;
unsigned long *stats = ipi_data[smp_processor_id()].stats;
Original:
void handle_IPI(struct pt_regs *regs)
{
- unsigned long *pending_ipis = &ipi_data[smp_processor_id()].bits;
- unsigned long *stats = ipi_data[smp_processor_id()].stats;
+ unsigned int cpu = smp_processor_id();
+ unsigned long *pending_ipis = &ipi_data[cpu].bits;
+ unsigned long *stats = ipi_data[cpu].stats;
Upstream includes commit 7ecbc648102f which removes the old_regs variable.
That doesn't mean it can be removed in the backport.
