Linus, Thanks for pointing this out and Guenter thanks for testing.
I ack the issue on OpenRISC and will send a patch for review in a day or so. I'll also do an audit of openrisc to see if we have similar issues.
Next to access_ok() is __addr_ok() which seems to have the similar quoting issue, but I don't see it being used anywhere, it's also defined and not used on: arm, x86 and csky. It is used on SH.
OK to remove __addr_ok()?
