Subject: [PATCH] riscv: Fix NR_CPUS range conditions

The conditions reference the symbol SBI_V01, which does not exist. The
correct symbol is RISCV_SBI_V01.

Yeah, huh. It never occurred to me that we don't have some sort of symbol
referencing checking in kconfig. Or maybe we do and I just don't know how
to enable it? Anyway, this issue made me wonder how many more dangling
references we may have. I wrote a script to look for them and found 29,
including this one. I'm not exactly sure how to report them since they
touch so many different places. For now, I've opened this kernel BZ

kismet, but that does the opposite. Randy Dunlap is the only person I
see fiddling with that stuff usually, so perhaps he knows? +CC them
either way.

Thanks. This is on fixes, it's sort of jumping the queue (I've got a
bunch of stuff still staged from last week, but thanksgiving screwed up
the flow) but it's small enough it doesn't seem worth waiting.
