 hardirqs_enabled

Hi, all

Sorry for everybody concerned. Please ignore this patch.

I sent this patch without my supervisor's ACKed. I missed a lot of 
important information.

I'm a newbie for submitting patches to community and I should have sent 
a valid patch under

my supervisor's guidance.

Execuse me, everyone.

Qi Hou
