vmware test patch

Can you try the following patch? Note this is for the warning only.
Comment 3 Christopher Meng 2015-07-17 04:08:57 UTC 
Hi,

I will try to patch the kernel in this afternoon since I'm running out of space while compiling patched version.

PS. Should I add a reviewed by sign?

Thanks.

This bug is pretty old and I think this has been fixed. Closing now, feel free to reopen.
