x86 maintainers, can you please ack or nack this patch?

This looks trivially correct, but I don't want to apply this patch
without an ack since this is under arch/x86.

Thanks,
Wei.

Just a heads up:

https://git.kernel.org/tip/775d3c514c5b2763a50ab7839026d7561795924d

and that one is a fix so it'll go to Linus now.

Which means, you'll have to use Linus' tree with that fix as a base and
queue everything ontop.
