What's the "-next" for?  This seems appropriate for an RC to me, as it's a
build fix.

Thanks for your review, this patch and "[PATCH -next] riscv: perf: 
RISCV_BASE_PMU

should be closeable", I fix the issue based on linux-next, so add the 
next prefix ; )

and we also found some another build issue when add RISCV arch to huawei 
build robot,

will send out the patches later.

OK, makes sense.  I've put it on fixes.
